kbuild: mergeconfig: fix "jobserver unavailable" warning
commit de4619937229378e81f95e99c9866acc8e207d34 upstream.
If "make kvmconfig" is run with "-j" option, a warning message,
"jobserver unavailable: using -j1. Add `+' to parent make rule.",
is displayed.
$ make -s defconfig
*** Default configuration is based on 'x86_64_defconfig'
#
# configuration written to .config
#
$ make -j8 kvmconfig
Using ./.config as base
Merging ./arch/x86/configs/kvm_guest.config
[ snip ]
#
# merged configuration written to ./.config (needs make)
#
make[2]: warning: jobserver unavailable: using -j1. Add `+' to
parent make rule.
scripts/kconfig/conf --oldconfig Kconfig
