package/gcc: fix fortran support

Browse Source 
Fortran depends on libquadmath when available, make the buildroot
toolchain option depends on this new hidden symbol,

[Vincent: only do "HOST_GCC_FINAL_USR_LIBS += libquadmath" for i386 and
x86_64, otherwise it will fail saying "libquadmath.a: file not found"]
