Subject: [Avr-gnu-toolchain] [uClibc PATCH] Fix inverted logic in
__compare_and_swap in linuxthreads.old
If the old value equals the value in memory, the result should be
TRUE, not FALSE.

Subject: [PATCH] Fix resolve when identical IPv4 and IPv6 hosts are defined in /etc/hosts
This patch will fix a problem when the same host is defined with both IPv4 and
IPv6 entries in /etc/hosts. Previous only the first of these host would work,
as uClibc would read the /etc/hosts file from top to bottom, failing if the
first hit did not match the IP type.
Now uClibc will continue reading, even if the first correct entry name, but wrong IP
type fails. Thus, allowing a second correct entry name with correct IP type
will result in a name resolve.

Subject: [Avr-gnu-toolchain] [uClibc PATCH] Load GOT pointer at the
beginning of .init and .fini
I don't know why this seems to have worked before, but the .init and
.fini sections typically consist of a bunch of mcalls using r6 as the
base pointer. This can cause "interesting" behaviour when r6 hasn't
been initialized to point to the GOT.
