Many thanks for the much needed reply, please see below ...
BTW, you or may or may not be interested to know that since subscribing to
this and the libav-user list, I've been receiving phishing spam.

I've never got involved with git, as I'm not interested in bleeding edge. I
just want to get ffmpeg working on this particular device.

AFAICR I did, and it made no difference to the end result. Will try again,
though.

At least the --disable-mipsdspr1 and --disable-mipsdspr2 are nesessary,
otherwise further compile errors occur.

I think you mean MIPS? (But, BTW, the only way I could get FFMPEG to
compile on another device, a Zyxel NAS221 running on Ox810, ARM926EJ-S rev 5
(v5l) 183 BogoMIPS, was to disable many ARM
optimisations, --cpu=armv5te --disable-armv6 --disable-armv6t2 --disable-neo
n --disable-vfp --disable-vfpv3; however that is history, FFMpeg is working
well on that device now.)

Ok, here's the output from a rerun with the configuration changes you have
suggested:
First for finds of fminf (I'd already got that far, so I'll include them
anyway, before following your advice):
Searching for: fminf in *.*
config.log(3269): fminf
config.log(3539): fminf
config.log(8567): check_mathfunc fminf 2
config.log(8572): 2 float foo(float f, float g) { return fminf(f, g); }
config.log(8578): ffconf.8kYhEsYK.c:(.text+0x20): undefined reference to
`fminf'
libavutil\libm.h(86): #undef fminf
libavutil\libm.h(87): static av_always_inline av_const float fminf(float x,
float y)
doc\config.texi(198): @c @set have-fminf no
Found 8 occurrence(s) in 3 file(s)
Next you wanted a section of config.log as follows (the entire file is
appended):
check_mathfunc fminf 2
check_ld cc
check_cc
BEGIN /share/external/USB_DRIVE_A1/.tmp/ffconf.8kYhEsYK.c
1 #include <math.h>
2 float foo(float f, float g) { return fminf(f, g); }
3 int main(void){ return (int) foo; }

Finally, here's the the results of a new attempt including your suggested
configuration changes:

Additionally, I've just discovered this. Unfortunately, the rather arcane
posting restrictions means that I can't send the whole file, but here is a
section that looks relevant to the problem, and there is a link below to
download the package if that should be required ...

5.44 Other built-in functions provided by GCC
=============================================
GCC provides a large number of built-in functions other than the ones
mentioned above. Some of these are for internal use in the processing
of exceptions or variable-length argument lists and will not be
documented here because they may change from time to time; we do not
recommend general use of these functions.
The remaining functions are provided for optimization purposes.
GCC includes built-in versions of many of the functions in the standard
C library. The versions prefixed with `__builtin_' will always be
treated as having the same meaning as the C library function even if you
specify the `-fno-builtin' option. (*note C Dialect Options::) Many of
these functions are only optimized in certain cases; if they are not
optimized in a particular case, a call to the library function will be
emitted.
Outside strict ISO C mode (`-ansi', `-std=c89' or `-std=c99'), the
functions `_exit', `alloca', `bcmp', `bzero', `dcgettext', `dgettext',
`dremf', `dreml', `drem', `exp10f', `exp10l', `exp10', `ffsll', `ffsl',
`ffs', `fprintf_unlocked', `fputs_unlocked', `gammaf', `gammal',
`gamma', `gettext', `index', `isascii', `j0f', `j0l', `j0', `j1f',

`printf_unlocked', `rindex', `scalbf', `scalbl', `scalb', `signbit',
`signbitf', `signbitl', `significandf', `significandl', `significand',
`sincosf', `sincosl', `sincos', `stpcpy', `strdup', `strfmon',
`toascii', `y0f', `y0l', `y0', `y1f', `y1l', `y1', `ynf', `ynl' and `yn'
may be handled as built-in functions. All these functions have
corresponding versions prefixed with `__builtin_', which may be used
even in strict C89 mode.
The ISO C99 functions `_Exit', `acoshf', `acoshl', `acosh', `asinhf',
`asinhl', `asinh', `atanhf', `atanhl', `atanh', `cabsf', `cabsl',

`truncf', `truncl', `trunc', `vfscanf', `vscanf', `vsnprintf' and
`vsscanf' are handled as built-in functions except in strict ISO C90
mode (`-ansi' or `-std=c89').
