Debian reproducible: re-enable PGO and LTO when building gcc-* and binutils.

This was a "temporary" workaround to guage the impacts of Profile
Guided Optimization and Link Time Optimization on gcc and binutils,
and it definitely helped at the time, but also gives us a false sense
of reproducibility!

Leave "nocheck" for now, as it often triggered build timeouts.

This partially reverts c51432de52c1dde9eb2c374b0656ab8b58c4b9c3.
