Another external toolchain support solution
* In toolchain/external-toolchain/ext-tool.mk, copy the contents of
the sysroot directory to the staging dir.
* In package/Makefile.in, add a --sysroot CFLAGS pointing to the
staging dir
* Remove the CFLAGS and LDFLAGS definition from
TARGET_CONFIGURE_OPTS. I haven't investigated exactly why, but with
these options, DirectFB fails to build because it cannot find
PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP, even if DirectFB's Makefile
properly sets -D_GNU_SOURCE.
I have already sent this patch on December, 2nd to the mailing-list,
but got no feedback. So let's commit and see what happens :-)
