Indeed, the rust support is the cause of the issue:

add74f8473c5ca7d8947c760ff355df991a259bb (HEAD) Rust support
0d02ec6b3136c73c09e7859f0d0e4e2c4c07b49b (tag: v5.12-rc4, s390/master,
s390/linux/master) Linux 5.12-rc4

While v5.12-rc4 is OK add74f8473 produces the error.

There is additional issue that I noticed: dummy tools does not work
seamlessly with O=

$ make CROSS_COMPILE=$(pwd)/scripts/dummy-tools/ O=/scratch/ppc64/ V=1 ARCH=powerpc allmodconfig > /dev/null
which: no elfedit in (/home/michal/linux-2.6/scripts/dummy-tools)

$ make CROSS_COMPILE=scripts/dummy-tools/ O=/scratch/ppc64/ V=1 ARCH=powerpc allmodconfig > /dev/null
which: no elfedit in (./scripts/dummy-tools)
scripts/Kconfig.include:39: compiler 'scripts/dummy-tools/gcc' not found
make[2]: *** [/home/michal/linux-2.6/scripts/kconfig/Makefile:63:
allmodconfig] Error 1
make[1]: *** [/home/michal/linux-2.6/Makefile:636: allmodconfig] Error 2
make: *** [Makefile:222: __sub-make] Error 2

Perhaps linking dummy-tools into the target directory would be a good
idea?

Thanks

Michal
