Subject: scons: wait on subprocess' completion
X-Git-Tag: upstream/18.1.0~8181
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9f6110ad327275fecc68248c1d6bd85f6b3d111c;p=platform%2Fupstream%2Fmesa.git

scons: wait on subprocess' completion

Windows doesn't allow you to move a file that's opened, and Popen()
doesn't wait on its subprocess' completion before returning, which leads
to broken Windows build.

Fixes: 3fd425aed764fb771f2f "build systems: uniformize git_sha1.h generation"
