Hi,

perf cross-compile error dual to fixdep is not a host executable, first bad commit
is 7c422f557266("tools build: Build fixdep helper from perf and basic libs")

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

Thank you

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.

could you please provide output from that build with 'JOBS=1 V=1'

last chance before I kick myself to actualy setup cross compiling :-\

He Kuang the new fixdep tool breaks cross compiling. The reason
is it wouldn't get compiled under host arch, but under cross arch
and failed to run.

We need to add support for host side tools build, meanwhile
disabling fixdep usage for cross arch builds.
