Thomas Petazzoni 71719b91ee package/gdb: also disable gprof
When gdb is built from sources fetched from Git, it contains both the
gdb and the binutils code base. In order to really build only gdb, we
disable a number of binutils components in the
GDB_DISABLE_BINUTILS_CONF_OPTS variable: --disable-binutils,
--disable-ld, --disable-gas, etc. However, gprof was still being
built, so disable it as well.
