Question: glibc, eglibc and uclibc map to 'libc6' at package time, how do we get that into
meta-toolchain? I added this:

LIBC_linux = "glibc"
LIBC_linux-uclibc = "uclibc"
LIBC_linux-gnueabi = "glibc"
LIBC_linux-uclibcgnueabi = "uclibc"

which works fine for glibc and uclibc, but not for eglibc. To make it worse, we also need
(e)(g)(uc)libc-dev in the toolchain....

regards,

Koen
