Subject: configure: Add 'mkdir build' check
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=f160a5b25b33b69b089815cfd435aa3199497984;p=qmiga%2Fqemu.git

configure: Add 'mkdir build' check

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.
