* 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 :-)

Fix issues with binary external toolchains
Fix two problems encountered while using an external binary toolchain
generated by crosstool-ng:
- Don't remove the ending / in LIB_DIR, otherwise find $LIB_DIR
-maxdepth 1 doesn't find any file in the case LIB_DIR is a symbolic
link and not a directory.
For some reason, find -maxdepth 1 doesn't have the same behaviour
on directories and symbolic links. Demonstration:
$ mkdir foobar
$ touch foobar/t1
$ touch foobar/t2
$ ln -s foobar barfoo
$ find foobar -maxdepth 1 -name 't*'
foobar/t1
foobar/t2
$ find barfoo -maxdepth 1 -name 't*'
$ find barfoo/ -maxdepth 1 -name 't*'
barfoo/t1
barfoo/t2
* Make sure the libraries are writable, otherwise the strip operation
might fail. The library files may not be writable if the toolchain
is not writable (which may happen if one wants to prevent anyone
from overwriting the toolchain, which is done by crosstool-ng, for
example).
