[git commit 0_9_30] Build posix_fadvice{64} only when UCLIBC_HAS_ADVANCED_REALTIME is set.

[Khem Raj]

commit: http://git.uclibc.org/uClibc/commit/?id=77ee5b304e2964a2e3b98122dc9d7cab4e04e622
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/0_9_30

Right now for ARM, MIPS, Xtensa and powerpc posix_fadvise
routines are included conditionally. They should only be
enabled when UCLIBC_HAS_ADVANCED_REALTIME is set. Also fix
code style in powerpc/posix_fadvise64.c
