942388 - MOZ_OBJDIR interprets paths with tilde literally

Status: NEW

(Firefox Build System :: General, defect)

Description

[Kelsey Gilbert [:jgilbert]]

I have a ramdisk mounted at ~/ram.
To build into it, I tried using:
mk_add_options MOZ_OBJDIR=~/ram/objs/obj-dbg

Builds seem to work fine, and seemingly used to build into this location properly. Now though, it seems to build into ./~/ram, not /home/jgilbert/ram.

./mach clobber was also not working consistently, I believe because sometimes I call it at mozilla/central/mach, and other times it's called via a forwarder script at mozilla/mach. (Only a looks like a bug when using relative paths for the objdir, as is accidentally the case here)
