Sorry, this patch should have been marked as RFC.

Ok, I'm fine with this solution.

I wanted to show what I had done in order to compile gdb in shared only case
without re-add --enable-static in GDB_CONF_OPTS.
I agree patching gdb is not an elegant solution.

What I have observed since shared only build are available, is that some
packages pass --disable-static or disable static build for their build-in
libraries even when they should be build statically :-/
