Configuring gcc with --enable-target-optspace (which causes gcc to
append "-g -Os" to the default CFLAGS_FOR_TARGET and so force libgcc
etc target libraries to always be optimised for size) dates back to
the very first commit in oe-core git in 2005 (for gcc 3.4.3).
Configuring gcc with --enable-target-optspace is not done widely
elsewhere (it's not used for Ubuntu or Fedora host gcc, the Linaro
binary toolchain or in Buildroot since early 2015). Sometime around
gcc 4.5.x it caused problems for powerpc and so was disabled for that
architecture:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810
This patch removes --enable-target-optspace completely (ie powerpc is
no longer a special case) and allows optimisation of libgcc etc to be
controlled directly by the flags present in TARGET_CFLAGS.

No significant changes.
Binaries which link statically with libgcc all grow a little
(somewhere between 10 and 50 bytes).
libgcc_s.so.1 itself grows by approx 1%:
text data bss dec hex filename
114896 516 56 115468 1c30c libgcc_s.so.1 (-Os)
116148 516 56 116720 1c7f0 libgcc_s.so.1 (-O2)
libssp, libstdc++, libgomp and libatomic all ignore the
--enable-target-optspace configure option, so are not affected.
(Results from an armv7ve build).

Thanks, I am ok with this change. Can you also report a qemuppc build with this
change and make sure it boots ?

No issues seen booting qemuppc core-image-minimal built from today's
