It was the cross-compiler toolchain I was interested in; which cross-compiler?
The gcc-arm that is in the Ubuntu repos, or one of the others? (there are
many...!)

Specifically, I was asking what X11 server is running on your target system,
and for which you are cross-compiling. Is it the XOrg server, and if so, is it
a "full" server, or one of the cut down ones (KDrive/TinyX stuff) or is it an
embedded X11-work-alike server, e.g. nano-X or something?

OK - have you used this cross-compilation toolchain before? Have you
successfully deployed any code to your target using it?

OK - and you are sure you are looking in the header files of the
cross-toolchain, not in the header files of the host system?
In any case, the reference existing in the header files does not tell us much,
it is what is in the libs themselves that matters at the end of the day.

Well, on your host system, type this:
fltk-config --ldstaticflags
and fltk-config will tell you the flags it would use to link your application
(albeit for the host, you may be able to get it to tell you about your
cross-target too, though that would be trickier... It is likley to be much the
same, however. Probably!)
Here, I get:
$ fltk-config --ldstaticflags
/home/imacarthur/src/fltk-1.3/lib/libfltk.a -lXext -lXft -lfontconfig
-lXinerama -lpthread -ldl -lm -lX11
Of these, the likely X11 libs are X11 and Xext, which will resolve to libX11.so
and libXext.so (or possibly resolve to libX11.a and libXext.a in a fully static
link... you probably don't want that though I'd guess...)
And note that link order is important, so you need to link them in that order
or it may not work!
So, you find out what is in these libs by passing them to nm, and see what it
says, e.g.
nm /the/path/to/libX11.a
or
nm -D /the/path/to/libX11.so
or, if you know the symbol you want to look for, try:
nm /the/path/to/libX11.a | grep XIMOfIC
which, on this box returns:
00a8b520 T XIMOfIC
The interesting part here is the "T" in the middle, this tells us that this
library defines this symbol.
If you don't see the symbol at all, or it is in there but has any letter other
than T, then the symbol is *not* provided by the lib...
This is all way off-toic for fltk though, this is looking a lot more like
there's something odd in your X11 libs, so you may get more mileage from trying
to track that down.
