toolchain: Add uClibc 0.9.30.3, remove older 0.9.30.x

As the 0.9.30.x stable releases only contain bugfixes, there isn't much
sense in using the older 0.9.30.x releases instead of .3, so use a single
0.9.30.x config similar to how we do it for the kernel headers.

-Subject: [PATCH 09/15] malloc: fix race condition and other bugs in the no-mmu malloc
-
-Fixes multiple race conditions on mmb list. This was done by
-making the mmb_heap_lock into a recursive lock and making the
-regular heap_lock extend to cover the mmb heap handling.
-
-Also move the new_mmb allocation up to before the mmb list is
-iterated through to find the insertion point. When the mmb_heap
-also runs out and needs to be extended when the regular heap is
-just extended, the mmb list could be messed up.
