[SENT UPSTREAM] uclibc: disable parallel build for uClibc 0.9.31

This is only required for uClibc 0.9.31 and this veriosn is only used by
AVR32 so could be safely removed together with AVR32.

Even 0.9.32 builds well in parallel (at least on x86) so IMHO there's no need
in >= 0.9.33, just disable for a particular broken version.

[SENT UPSTREAM] uclibc: clean-up test suite build command

Starting from uClibc 0.9.32 this cleaned-up command builds tests flawlessly.
For 0.9.31 it lead to build failure, but assuming there're close to zero
users who is going to test outdated uClibc library on obsolete
(in Buildroot) AVR32 architecture I thin it worth applying.

Still it's possible to have 2 variants at the same time until AVR32 is not gone:
1. Old implementation used strictly for uClibc 0.9.31
2. New implementation for all other versions

[SENT UPSTREAM] binutils: disable makeinfo

makeinfo is known to cause problems when building old texi files with more
recent host makeinfo.

In particular binutils-2.18 won't build on Fedora 20 without this change.

Even though more up to date binutils does build without this change there's
no guaranty it will with bump of host makeinfo in the future.
