[Patch] Allow SECTION_FLAGS to be overridden by EXTRA_CXX_FLAGS

- Subject: [Patch] Allow SECTION_FLAGS to be overridden by EXTRA_CXX_FLAGS
The attached patch allows the configure switch:
--enable-cxx-flags='-fno-data-sections -fno-function-sections'
to work by reversing the order of @EXTRA_CXX_FLAGS@ @SECTION_FLAGS@
-fdata-sections and -ffunction-sections appear to offer no advantage
on mingw32 target but do make larger executeables.
