bootstrap/106482 - document minimal GCC version
There's no explicit mention of what GCC compiler supports C++11
and the cross compiler build requirement mentions GCC 4.8 but not
GCC 4.8.3 which is the earliest known version to not run into
C++11 implementation bugs. The following adds explicit wording.

known to work.
