Go in your gcc source tree, in gcc-<version>/gcc/config/arm.  That where all
the magic is defined.  The functions you're looking for are defines in
lib1funcs.asm.  You could link this file with the proper defines directly
into your work.  Alternately you could try to tell gcc to build and install
a FIC variant of the library when actually building itself. To do so you
need to modify the file t-arm-elf where many examples are currently
commented out.  Then rebuilding and reinstalling gcc will provide you with
all variants of libgcc.a you specified.
