The easy (and portable) way to find libgcc is to simply ask gcc
where it is. A command like:
gcc -print-libgcc-file-name
will print the location of the libgcc file. You can also use this
directly in your makefile with something like:
LIBGCC := $(shell $(CC) -print-libgcc-file-name)
and then adding ${LIBGCC} to the end of the ld line in your make
file.

I have never had a problem using the math library without libc. In
fact, I have never successfully linked against libc at all for an RTLinux
module. Hmmm....
