these directives. Package-specific flags should be set using the
directives, not the environment variables, so that builds work in
unmodified environments. Flags obtained from environment variables
are not subject to the security limitations described above.

All the cgo CPPFLAGS and CFLAGS directives in a package are concatenated and
used to compile C files in that package. All the CPPFLAGS and CXXFLAGS

// is considered authoritative, but non-trivial improvements to that
// should be mirrored here.
