Unfortunately, there is no way to specify arch-specific
no-dot-config-targets.
This patch made me upset a bit.
Some solutions.
[1] Decide list_% is the right thing
[2] Invent a way to add arch-specific no-dot-config-targets
For example, add arch/mips/no-dot-config
Then, append it as follows:
no-dot-config-targets := clean mrproper distclean \
cscope gtags TAGS tags help% %docs
check% coccicheck \
$(version_h) headers_% archheaders archscripts \
kernelversion %src-pkg
kernelversion %src-pkg $(shell cat
arch/$(SRCARCH)/no-dot-config)
(This needs to tweak the top Makefile a bit more)
[3] (Ab)use the existing name convention
For example, if you rename as follow,
list_generic_defconfigs -> list_generic_defconfig
list_legacy_defconfigs -> list_legacy_defconfig
This works without adding 'list_%s'
The hack of arch/mips/Makefile is so ugly,
but adding two more would not hurt.
