Hi,

commit

Cross-compiling an aarch64 target on x86_64 host, error like this:
$ make ARCH=aarch64 O=xx/aarch64 CROSS_COMPILE=aarch64-linux-gnu
...
make[3]: *** [xx/aarch64/parse-utils.o] Error 126
make[3]: *** Waiting for unfinished jobs....
/bin/sh: xx/aarch64//fixdep: cannot execute binary file
$ uname -a
x86_64 x86_64 x86_64 GNU/Linux
$ file xx/aarch64//fixdep
xx/aarch64//fixdep : ELF 64-bit LSB executable, ARM aarch64, version 1
(SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for
GNU/Linux 3.7.0, not stripped
hum, we need fixdep to stay the host arch.. I should have seen it :-\
could you please check attached patch?
thanks,

It does not work, 'fixdep' still be compiled as target executable.
Thank you.
