HOWTO sync branch:
1) Generate patch and fix up their path

 git format-patch --subject-prefix=klibc -N <changeset>..

Path fixup:
 perl -i -pe 's#^([-+]{3} [ab]/)src/#$1#g' 00*patch

2) Import patches on by one
 git am --directory="usr/dash" --exclude="usr/dash/configure.ac" \
	--exclude="usr/dash/ChangeLog" --exclude="usr/dash/dash.1" \
	--exclude="usr/dash/Makefile.am" --exclude="usr/dash/mksignames.c" \
	--whitespace=fix -k -i -s ../dash/000X-foo.patch

The only changes made are the addition of config.h, Kbuild usage,
the omition of Changelog and manpage and automatic whitespace fixups.

Generate klibc config.h in dash repository:
 automake --add-missing
 autoreconf
 ./configure CC=klcc
