[meta-oe][PATCH 109/109] libstemmer: fix buildpaths QA warning in libstemmer-dbg package

GNUmakefile hardcodes its own CFLAGS= assignment (patched by
0001-Build-so-lib.patch to add -fPIC for the shared-lib build). As a
plain makefile variable, that assignment overrides the CFLAGS bitbake
exports into the build environment -- including the -ffile-prefix-map
flags from DEBUG_PREFIX_MAP. Without those, -g debug info in the
compiled snowball/stemwords/libstemmer.so binaries embeds the absolute
build-tree path, tripping the buildpaths QA check on the -dbg package:

  ERROR: libstemmer-3.1.1-r0 do_package_qa: QA Issue: File
  /usr/bin/.debug/snowball in package libstemmer-dbg contains
  reference to TMPDIR [buildpaths]

Pass CFLAGS via EXTRA_OEMAKE instead, which oe_runmake places on the
make command line and therefore does take precedence over the
makefile's own CFLAGS= assignment.

Verified via cleansstate rebuild: log.do_package_qa no longer contains
any buildpaths warnings, and `strings` on the rebuilt snowball debug
binary no longer contains any build/tmp/work host paths.
