[Qemu-devel] [PATCH] configure: create fsdev/ directory

[Michael Tokarev]

In some cases when building with parallelism (make -jN),
build fails because the directory where output files are
supposed to be does not exist.  In particular, when make
decides to build virtfs-proxy-helper.1 before other files
in fsdev/, build will fail with the following error:

perl -Ww -- BUILDDIR/scripts/texi2pod.pl 
BUILDDIR/fsdev/virtfs-proxy-helper.texi fsdev/virtfs-proxy-helper.pod && 
pod2man --utf8 --section=1 --center=" " --release=" " 
fsdev/virtfs-proxy-helper.pod > fsdev/virtfs-proxy-helper.1
opening "fsdev/virtfs-proxy-helper.pod": No such file or directory

Create the `fsdev' subdir the same way as other "conditional"
subdirs (eg, dtc or pixman) are created in configure.

Might be better to extract all dirs from $tools and other
common vars and run mkdir on all of these, but this needs
some review/restructuring first.
