c24517c9dd PowerPC: Cleaning up uneeded sqrt routines
For PPC64, all the wrappers at sysdeps are superfluous: they are
basically the same implementation from math/w_sqrt.c with the
'#ifdef _IEEE_LIBM'. And the power4 version just force the 'fsqrt'
instruction utilization with an inline assembly, which is already
handled by math_private.h __ieee754_sqrt implementation.

5e6a4d4b9e PowerPC: Adjust multiarch Implies for PowerPC64
This patch adds Implies files on multiarch folder for POWER chips so
multirach is enabled when building with --with-cpu and powerN
option.

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.
