This commit breaks qemu-arm in a debian/stretch/armhf chroot.

When I try to run the ltp-full-20180515 test suite it hangs at the end
of the configuration phase, in config.status:

...
config.status: creating include/mk/config.mk
config.status: creating include/mk/config-openposix.mk
config.status: creating include/mk/features.mk
config.status: creating lib/ltp.pc
config.status: creating m4/Makefile
config.status: creating execltp

# ps -ef|grep qemu
...
root     21961 21959  2 17:16 pts/0    00:00:04 //qemu-arm /bin/bash
./config.status
root     22354 21961 97 17:18 pts/0    00:00:32 //qemu-arm /usr/bin/mawk
-f ./confneVYre/subs.awk

Any idea?

Thanks,
Laurent
