772201 - Webrtc breaks builds with symlinked objdirs

Status: RESOLVED FIXED

Description

[Randell Jesup [:jesup]]

The assumption is that this is due to use of relative paths to try to get 'out' of the objdir.  Likely the problem is largely in mozmake.py; perhaps in configure.in, media/webrtc/Makefile.in or related spots.

This appears to fix all the ../* paths in topsrcdir/srcdir/VPATH in gyp-generated Makefiles.

A grep on the makefiles showed no relative paths left after applying this patch and generating an objdir through a symlink, and it builds.

FWIW: my Linux 64 bit SeaMonkey debug builds are also affected by this bug and this patch does help indeed.

Uses OS to decide to do absolute paths or not (always relative on windows to make it work with 'make' as well as 'pymake').

I'll fix the missing space in the first change before checkin
