[Buildroot] [git commit] gdb: get rid of host-texinfo dependency

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=12306a81f8edc6db84e4e3c5e58e707ba9e4c9f5
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The host-texinfo dependency in gdb/host-gdb was added because gdb insisted
in building info documentation in recent versions, and we want to avoid
'makeinfo' to be present on the build system.

However, there is another solution that does not require actually building
host-texinfo: instruct the makefiles to use a dummy makeinfo command
('true').
