[OE-core] uclibc?

[Phil Blundell]

I've just been trying to build a uclibc-based system from the current
head of oe-core but this doesn't seem to be something that works
entirely smoothly at the moment.  Does anybody have a patchset to fix
the uclibc recipes, or is anybody working on such a thing?

Issues I've encountered thus far are:

- fatal errors from insane.bbclass due to missing LIC_FILES_CHKSUM in
uclibc recipes

- a bunch of slightly-bogus-looking bits in tclibc-uclibc.inc causing
"-uclibc" to get appended to ${STAGING_DIR_HOST} (seemingly twice!),
which was apparently breaking perl-native in some slightly obscure
fashion.

- uclibc-initial looks for gcc-initial in the wrong place.  I copied the
${STAGINGCC} bits from eglibc-initial to fix this.

- uclibc-initial installs itself into the wrong place.  I copied the
setting of do_populate_sysroot[sstate-outputdirs] from eglibc to fix
this.

- uclibc compile now fails at:
