f230c29b40 Avoid performance penalty in sparc optimized memcpy/memset. 
fmovd clears the current exception field in the %fsr, fsrc2
does not and therefore runs more efficiently on some cpus.

	values between float registers.

a88b64b9bb [PowerPC] Remove -ftree-loop-linear from Makefiles 
In the past the "-ftree-loop-linear" switch provided a measurable
improvement in performance for certain functions.  At some point it
was assigned as the responsibility of Graphite in GCC.  It has been
found that even with Graphite enabled these flags no longer perform
any appreciable improvement over the baseline.

Graphite now has some open bugs which need to be fixed in order for it
to provide measurable performance improvements but it lacks active
development.  As a result some compiler distributors may disable
Graphite.  If Graphite is disabled then building GLIBC will fail if
the "-ftree-loop-linear" switch is used.

This patch removes the use of "-ftree-loop-linear" as unnecessary.
