Not at all!  Someone else just asked that question!

Gladly.  I'd prefer, though, that you define a BUILD_LDFLAGS variable
and let the user set that directly rather than having a special
STATICALLY_LINKED.  It'd be a bit more general.

e.g. the user would set BUILD_LDFLAGS=-static,
and crosstool would stick LDFLAGS="$BUILD_LDFLAGS" on the
final gcc and binutils builds (and maybe glibc, too, since
it compiles a couple of helper binaries).

Or something like that...
