[Buildroot] [git commit] gdb: fix build of host-gdb 7.4

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=21aaa85608f1a98da7e6df76d1ce274076a03ef5
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The build of host-gdb 7.4 fails due to some texinfo issue. To avoid
that, use the same trick as is used for the target variant of gdb:
tell gdb that makeinfo is missing.
