[PATCH] Use output synchronization for make for clearer output

[PATCH] Use output synchronization for make for clearer output

[Sam James]

Pass --output-sync=line to make to avoid noise when multiple jobs
(especially configures) are running in parallel.

Gentoo and opensuse are both using this for building gcc/gdb/binutils
because it makes logs much more legible.

This looks very useful. Thanks. I extended it a bit to include all
parallel make commands and pushed it.

Cheers,
