[Buildroot] make clean behavior

[Thomas De Schampheleire]

Hi,

Is it intentional that 'make clean' is different depending on having a
.config file?

With .config there is a full clean:

rm -rf buildroot/output/host/usr/powerpc-buildroot-linux-gnu/sysroot
buildroot/output/target buildroot/output/images buildroot/output/host
buildroot/output/stamps buildroot/output/build
buildroot/output/toolchain buildroot/output/staging
buildroot/output/legal-info


but if you remove .config (and thus symbol BR2_HAVE_DOT_CONFIG) you
only have a partial clean:

rm -rf /repo/tdescham/reborn/buildroot-ppc/output/build
/repo/tdescham/reborn/buildroot-ppc/output/staging


Suppose you accidentally removed your .config, then you cannot easily
get a clean buildroot env anymore. The behavior is caused due to the
definition of variables like TARGET_DIR being inside a 'ifeq
($(BR2_HAVE_DOT_CONFIG),y)' statement.

I would propose to make sure that 'clean' works in all cases, by
moving the relevant variable definitions outside this if statement.

Best regards,
Thomas
