Changqing Li c32e635b23 mime.bbclass: fix post install scriptlet error
fix error during post uninstall:
%postun(shared-mime-info-data-2.0-r0.4.corei7_64): execv(/bin/sh) pid 78
+ '[' 0 = 0 ']'
+ set -e
+ '[' x '!=' x ']'
+ echo 'Updating MIME database... this may take a while.'
Updating MIME database... this may take a while.
+ update-mime-database /usr/share/mime
Directory '/usr/share/mime/packages' does not exist!
%postun(shared-mime-info-data-2.0-r0.4.corei7_64): waitpid(78) rc 78 status 100
warning: %postun(shared-mime-info-data-2.0-r0.4.corei7_64) scriptlet failed, exit status 1

when run post uninstall scriptlet, /usr/share/mime/packages has been
removed during unintall, while update-mime-database will check xml under
/usr/share/mime/packages.

workaround by create this dir before update, then remove it

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.
