So what's the clean solution?

Disabling gcc-inplace-math allows gmp to build, but then gcc6 still 
fails because it needs bzip2 to unpack isl, and it's not listed as a 
dependency.  ( This I consider a bug, since anyone can disable 
gcc-inplace-math as an option. )

My first sucessful workaround was to disable gcc-inplace-math and add a 
bzip2 dependency to gcc6.  I now have a partial bulk build rolling on 
CentOS 7 using gcc6.

I also had to add m4 and bzip2 to the long exemption list that was 
needed for gcc48:

GCC_REQD+=6.0

.endif  # GCC_REQD

Not sure yet if any of these deps are unique to gcc48 and could be 
pruned here.

Still just the beginning.  It remains to be seen how gcc6 will fare is 
the base compiler for a full bulk build.  I'll hopefully be able to 
report on that in about a week.

I'm trying gcc6 before gcc5 or gcc7, BTW, because it seems to be the 
most popular choice for a modern, but stable GCC.
