[vlc-devel] [PATCH 1/2] pkg-static.sh: improve I/O redirects

[Robert Mourning]

Redirecting I/O for each command instead of redirecting
files to stdin/stdout allows overwriting those files
without needing to close the corresponding file descriptors
to build on Windows Subsystem for Linux (from DrvFs).
