-extldflags='-ggdb -O3'. If any package in a build includes a .cc or
other file compiled by the C++ compiler, the go tool will use the
-extld option to set the host linker to the C++ compiler.

These defaults mean that Go-aware build systems can ignore the linking
changes and keep running plain 'cmd/link' and get reasonable results, but
they can also control the linking details if desired.
