[Buildroot] [PATCH] Depend autotools targets on host-ccache when BR2_CCACHE is enabled.

[Raúl Sánchez Siles]

In this case, autotools targets rely on $(TARGET_CONFIGURE_OPTS) which includes
ccached compiler.

This should not be necessary since host-ccache is added to the
BASE_TARGETS list in the Makefile at the root of buildroot.

Anyway, what was the issue and the 'make ...' call sequence that lead to it?

Maybe:

	make menuconfig
	make <somepackage>

i.e, not starting the complete build, but just the build of a given
package?

See also https://bugs.busybox.net/show_bug.cgi?id=5678, which seems to
be related.

Right.

In these cases, I rather suggest to build either a whole "small"
config, or at least the toolchain
before tweaking anything (packages, kernel or bootloader).

Note that if we want to allow this use case, it may require adding BASE_TARGETS
to all *-menuconfig and packages' targets.

I think we don't want to go this way.

Being able to do "make linux-menuconfig" right after "make menuconfig"
is a quite important use case, IMO. We should support that I believe.

linux-menuconfig already depends on "dirs" so that it can work properly
when ran after "make menuconfig" (when ccache is not enabled). But I
see that it also depends on linux-configure. Maybe we just need to make
the *-extract of all packages depend on $(BASE_TARGETS) or something
like that?

Indeed, something like that seems doing the tricks :)

I'll cook a patch and submit it.
