Use libc_ifunc macro for clock_* symbols in librt.
This patch uses the libc_ifunc macro to create already existing ifunc functions clock_getres, clock_gettime, clock_settime, clock_getcpuclockid and clock_nanosleep. If HAVE_IFUNC is defined, the macro COMPAT_REDIRECT uses the libc_ifunc macro. Furthermore some whitespace damage is cleaned. ChangeLog: * rt/clock-compat.c (COMPAT_REDIRECT): Use libc_ifunc macro.
