[OE-core][PATCH] gcsections: apply section removal also in C++, not only in C

[OE-core][PATCH] gcsections: apply section removal also in C++, not only in C

[Peter Marko]

From: Peter Marko <peter.marko@siemens.com>

Currently only CFLAGS contains sections optimizations.
This is used during C compilation.
C++ compilation uses CXXFLAGS instead.

I did not introduce CXXFLAGS_SECTION_REMOVAL because the options
are identical in C and C++, while adding it would add whole lot
of additional useless lines of code to maintain.

Hello Peter,

I have collected it but this patch should have gone to the poky mailing
list as this is for meta-yocto.
