[oi-dev] error trying to compile gcc47-libgmp

[Alexander Pyhalov]

Hello.

I have tried to build gcc47, but received

configure: error: Oops, mp_limb_t is 32 bits, but the assembler code
in this configuration expects 64 bits.
You appear to have set $CFLAGS, perhaps you also need to tell GMP the
intended ABI, see "ABI and ISA" in the manual.
gmake: *** 
[/export/home/build/srcs/oi-userland/components/gcc47-libgmp/build/i86/.configured] 
Error 1

$ uname -a
SunOS buildzone 5.11 testws i86pc i386 i86pc Solaris

$ isainfo
amd64 i386

This is Intel(r) Xeon(r) CPU           E5345  @ 2.33GHz machine, I am 
building in zone.

It seems that the following change solves this problem, but I'm just 
building gcc and haven't tested it yet.
