[osv-dev] [PATCH] build: don't fail build if pathname has space

2019-03-14 Thread Nadav Har'El
Ideally, the build shouldn't care what is the pathname of the build directory. But some parts of the build process use, for historical reasons and for convenience, full pathnames, and some of that code did not correctly handle the case where the pathname might contain spaces, and the build fails.
