gcc-configure-common.inc: drop --enable-target-optspace from configure
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. (From OE-Core rev: 686b266506a1a56fb68ab0f00d658787dd7fe4ce) Signed-off-by: Andre McCurdy <armccurdy@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
