[Buildroot] [PATCH v2] gdb: prevent installation of libbfd.so and libopcode.so

[Peter Seiderer <ps.report@gmx.net>]

The gdb install target installs dynamic versions of libbfd and
libopcode, accidentally overwriting the binutils provided versions
(gdb itself links against the bundled static ones to avoid
version problems, so the dynamic ones are un-needed).

Prevent the installation by using the '--disable-install-libbfd'
configure option.

Changes v1 -> v2:
  - enhance commit log (suggested by Thomas Petazzoni)
  - use --disable-install-libbfd instead of --disable-shared
