need -fPIC cc flag?

Subject: need -fPIC cc flag?
Authentication-results: sourceware.org; auth=none
Hi Everyone,

I kind of asked this question already, but I can't seem to get the
-fPIC as flag in the final gcc compilation. This is for mips with ssp
and uclibc. The problem complained about it:
/media/SSD/Reinoud/latest_crosstools/linux-mips/mipsel-coconut-linux-uclibc/bin/ld:
.libs/compatibility.o: relocation R_MIPS_HI16 against `__gnu_local_gp'
can not be used when making a shared object; recompile with -fPIC
as you can see below.
Any hints as to how I can get -fPIC inserted as a cflag argument?
