TARGET_C99_FUNCTIONS for powerpc

- Subject: TARGET_C99_FUNCTIONS for powerpc
This is an obvious patch we should have had a long time ago. glibc
has all the required functions, and now we even have support for 128 bit
long double. Fixes a bunch of testsuite failures. OK to apply mainline
and 3.4?
* rs6000/linux.h (TARGET_C99_FUNCTIONS): Define.
(OS_MISSING_POWERPC64): Move, and comment.
