[Buildroot] [PATCH v3 1/3] gdb: get rid of host-texinfo dependency

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

From: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com>

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').

v2: use INSTALL_TARGET_OPTS for target packages iso INSTALL_OPTS
(INSTALL_STAGING_OPTS not needed: INSTALL_STAGING != YES)
v3: fix INSTALL_TARGET_OPTS to include the actual 'install' make target
