[PULL 24/33] configure: Add 'mkdir build' check

[Thomas Huth <thuth@redhat.com>]

From: Dinah Baum <dinahbaum123@gmail.com>

QEMU configure script goes into an infinite error printing loop
when in read only directory due to 'build' dir never being created.

Checking if 'mkdir dir' succeeds prevents this error.
