Richard Purdie 91f838e036 oeqa/selftest/buildoptions: Improve ccache test
This test occisionally fails as m4 doesn't recompile, meaning the logfile test
then doesn't find mention of ccache.

To ensure m4 does recompile, clean m4 before force compiling it.

(Reading the test is confusing due to the test cleanup also involving a clean)

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.
