Subject: [PATCH] MIPS: fix *-pkg builds for loongson2ef platform
Since commit 805b2e1d427a ("kbuild: include Makefile.compiler only when
compiler is needed"), package builds for the loongson2f platform fail.
$ make ARCH=mips CROSS_COMPILE=mips64-linux- lemote2f_defconfig bindeb-pkg
[ snip ]
sh ./scripts/package/builddeb
arch/mips/loongson2ef//Platform:36: *** only binutils >= 2.20.2 have needed option -mfix-loongson2f-nop. Stop.
cp: cannot stat '': No such file or directory
make[5]: *** [scripts/Makefile.package:87: intdeb-pkg] Error 1
make[4]: *** [Makefile:1558: intdeb-pkg] Error 2
make[3]: *** [debian/rules:13: binary-arch] Error 2
dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
make[2]: *** [scripts/Makefile.package:83: bindeb-pkg] Error 2
make[1]: *** [Makefile:1558: bindeb-pkg] Error 2
make: *** [Makefile:350: __build_one_by_one] Error 2
The reason is because "make image_name" fails.
$ make ARCH=mips CROSS_COMPILE=mips64-linux- image_name
arch/mips/loongson2ef//Platform:36: *** only binutils >= 2.20.2 have needed option -mfix-loongson2f-nop. Stop.
In general, adding $(error ...) in the parse stage is troublesome,
and it is pointless to check toolchains even if we are not building
anything. Do not include Kbuild.platform in such cases.
