New Revision: 291666
URL: https://svnweb.freebsd.org/changeset/base/291666
Log:
Fix build on GCC 5.2 where, at least on PPC64, the compiler would
"optimize"
the malloc() + memset() in the local implementation of calloc()
into a call
to calloc(), helpfully turning it into an infinite loop. Clean up
some
unneeded flags on PPC64 while here.

I wanted to set -ffreestanding for rtld compilation, but considered
it only
a minor issue. Could you test this instead of -fno-builtin, please ?
Sure, I'll test it today.
-Nathan
-ffreestanding works just as well for this as -fno-builtin. Would you
like to make the change?
