gdb: fix builds with internal readline and no static libraries 

If gdb was configured to use the internal readline but static libraries were
disabled, gdb wouldn't dutifully not build libreadline.a which was a problem
when it tried to link with that library.

Solve this by ensuring --enable-static is passed to the readline configure.

If gdb is configured with --disable-static then this is dutifully passed to
readline which then disables libreadline.a, which causes a problem when gdb
tries to link against that.
To ensure that readline always builds static libraries, pass --enable-static to
the sub-configure.
