gcc: Upgrade 7.2 -> 7.3

The static PIE patch was updated by Juro Bystricky <juro.bystricky@intel.com>
to work with gcc 7.3.

This update from the stable gcc 7 branch includes the retpoline
functionality which is useful to assist with recent security issues.

Two backported patches were dropped as they're included in 7.3.

(From OE-Core rev: a4c1ede6876ad6b84ab2b3bece14bf0afdc9d6b7)
