[Patch, PowerPC/Darwin] Fix library export of long double symbols.
During 8.x, the rs6000 target-specific mangling was reorganised which uncovered
a long-standing bug in Darwin’s mangling for ‘IBM’ long double. Now the symbols
are correctly mangled, and we end up with a bunch of test link fails.
This patch adds the necessary subset of the Linux long double exports to Darwin’s
export table.

[ARM] Fix size-optimization-ieee testcase failure
On some version of dejagnu, options in RUNTESTFLAGS are appended to the
command-line and thus any -mfloat-abi=softfp or -mfloat-abi=hard in
there overwrite the -mfloat-abi=soft in the dg-options for
size-optimization-ieee-* tests. Test is still run though because
arm_soft_ok returns true if -mfloat-abi=soft is accepted, even if the
file is not compiled for softfloat due to a later -mfloat-abi on the

This patch adds a dg-skip-if to those tests to ensure they are not run

[ARM] Optimize executable size when using softfloat fmul/dmul
Softfloat single precision and double precision floating-point
multiplication routines in libgcc share some code with the
floating-point division of their corresponding precision. As the code
is structured now, this leads to *all* division code being pulled in an
executable in softfloat mode even if only multiplication is
performed.
This patch create some new LIB1ASMFUNCS macros to also build files with
just the multiplication and shared code as weak symbols. By putting
these earlier in the static library, they can then be picked up when
only multiplication is used and they are overriden by the global
definition in the existing file containing both multiplication and
division code when division is needed.
The patch also removes changes made to the FUNC_START and ARM_FUNC_START
macros in r218124 since the intent was to put multiplication and
division code into their own section in a later patch to achieve the
same size optimization. That approach relied on specific section layout
to ensure multiplication and division were not too far from the shared
bit of code in order to the branches to be within range. Due to lack of
guarantee regarding section layout, in particular with all the
possibility of linker scripts, this approach was chosen instead. This
patch keeps the two testcases that were posted by Tony Wang on the mailing
list to implement this approach and adds a new one.
