Remove ARM __GNUC_PREREQ(4,4) conditionals.
This patch removes conditionals in ARM code on __GNUC_PREREQ(4,4),
which were already obsolete even before the move from 4.4 to 4.6 as
minimum GCC version for building glibc.

Tested for ARM that installed shared libraries are unchanged by this
patch.

	* sysdeps/arm/sysdep.h [PROF && __GNUC_PREREQ(4,4)] (CALL_MCOUNT):
	Make definition conditional only on [PROF].
	[PROF && !__GNUC_PREREQ(4,4)] (CALL_MCOUNT): Remove conditional
	definition.
	[__GNUC_PREREQ(4,4)] (mcount): Make definition unconditional.
	[!__GNUC_PREREQ(4,4)] (mcount): Remove conditional definition.
