Martin Jansa c36fb625d1 perf: backport a fix for confusing non-fatal error
* add V=1 to make log.do_compile a bit more useful, with this it shows:
  /bin/sh '/OE/build/oe-core/tmp-glibc/work/qemux86_64-oe-linux/perf/1.0-r9/perf-1.0/tools/perf/trace/beauty/arch_errno_names.sh' x86_64-oe-linux-gcc  -m64 -march=core2 -mtune=core2 -msse3 -mfpmath=sse --sysroot=/OE/build/oe-core/tmp-glibc/work/qemux86_64-oe-linux/perf/1.0-r9/recipe-sysroot /OE/build/oe-core/tmp-glibc/work/qemux86_64-oe-linux/perf/1.0-r9/perf-1.0/tools > /OE/build/oe-core/tmp-glibc/work/qemux86_64-oe-linux/perf/1.0-r9/perf-1.0/trace/beauty/generated/arch_errno_name_array.c

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
