mk: rename ambiguous LDFLAGS variable

The LDFLAGS environment variable is usually indented for C the linker
flags which are not compatible with go -ldflags.

Use a more explicit GO_LDFLAGS variable instead. Allow adding extra
flags without overriding the default ones by specifying
GO_EXTRA_LDFLAGS.

This may break the build on some distros that rely on setting LDFLAGS to
change the default shareDir or version. They will have to switch to
GO_EXTRA_LDFLAGS.
