Jose Quaresma 03e2fa220c sstate: another fix for touching files inside pseudo
This patch is a fixup for 676757f "sstate: fix touching files inside pseudo"

running the 'id' command inside the sstate_unpack_package
function shows that this funcion run inside the pseudo:

 uid=0(root) gid=0(root) groups=0(root)

The check for [ -w ${SSTATE_PKG} ] and [ -O ${SSTATE_PKG}.siginfo ]
will always return true and the touch can fail when the real user
don't have permission or in readonly filesystem.

As the documentation refers:
- the file test operator "-w" check if the file has write permission
(for the user running the test).
- the file test operator "-O" check if you are owner of file

We can avoid this test running the touch and mask any return errors
that we have.

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.
