building gcc 5.3 with gmp,mpfr,mpc,isl in tree results in error relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object

[Daniel Letai <dani at letai dot org dot il>]

Hi,

I'm trying to build a gcc-5.3 package for rhel 6 x64 (based on gcc-5.3.1 
from koji) with the prerequisites in tree, as if after using the 
contrib/download_prerequisites but with newer versions of those libraries.

The exact error:

/opt/gnu/binutils/2.26/bin/ld: 
/home/rpmbuild/BUILD/gcc-5.3.1-20160212/obj-x86_64-redhat-linux/objlibgccjit/./isl/.libs/libisl.a(isl_val_gmp.o): 
relocation R_X86_64_32 against `.rodata.str1.1' can not be used when 
making a shared object; recompile with -fPIC

error: Bad exit status from /var/tmp/rpm-tmp.Qe5BHa (%build)


RPM build errors:
    Bad exit status from /var/tmp/rpm-tmp.Qe5BHa (%build)


Since gcc/configure doesn't accept -fPIC, I'm not sure how to proceed - 
How do I tell gcc configure to pass -fPIC to just the isl library, and 
only when building objlibgccjit?
Any help would be appreciated, thanks.

I'd like to mention that the installation failed with the versions from 
contrib too


My current environment:
RHEL 6.7 x64
binutils 2.26 (compiled from source)
GMP 6.1.0
MPFR 3.1.3 (with latest "allpatches" applied)
MPC 1.0.3
ISL 0.16

My configure looks like:
