When I tried to build a broadcom chipset target with 2013.02 on Fedora 19, and met a compilation error when installing gdb to the target. The error is that the gdbint.texinfo files can't be correctly parsed:
./gdbint.texinfo:38: misplaced {
./gdbint.texinfo:38: misplaced }
make[7]: *** [gdbint.info] Error 1
....
make[7]: *** [gdb.info] Error 1
make[6]: *** [subdir_do] Error 1
make[5]: *** [install-only] Error 2
make[4]: *** [install] Error 2
make[3]: *** [install-gdb] Error 2
make[2]: *** [install] Error 2

The reason is that host-texinfo isn't compiled yet, to fix we need to add the dependency in gdb.mk

ifeq ($(BR2_PACKAGE_GDB_DEBUGGER),)
GDB_SUBDIR = gdb/gdbserver
HOST_GDB_SUBDIR = .
else
GDB_DEPENDENCIES = ncurses
endif

GDB_DEPENDENCIES += host-texinfo
