OK, continuing with the test. Specifying CPPFLAGS and LDFLAGS
makes the external libraries detected as follows:
$ env AUTOCONF_VERSION=2.69 AUTOMAKE_VERSION=1.16 autoreconf -i
$ ./configure --prefix=$HOME \
CC=cc CPPFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib
[...]

However, the build eventually fails with a linking error:
/bin/sh ../libtool --tag=CC --mode=link cc -g -O2 -fstack-protector-strong
-Wall -Wmissing-prototypes -Wstrict-prototypes -avoid-version -module
-L/usr/local/lib -fstack-protector-strong -Wl,--as-needed -o sox sox.o

ld: error: undefined symbol: lsx_malloc

Indeed, none of the input files defines lsx_malloc;
it is defined in libsox.so
$ nm .libs/libsox.so.3.0 | grep lsx_malloc
00042a30 T lsx_malloc
but that is not one of the inputs. Adding .libs/libsox.so.3.0
as an input to the above line make it link as expected.
