Nick Alexander 2f109387cc Bug 1707030 - Return to having NSDISTMODE=copy impact INSTALL. r=firefox-build-system-reviewers,mhentges 
This reverts [part of Bug
1255485](https://hg.mozilla.org/mozilla-central/rev/5888578c22f8dc006cfd6a405c9fc53b2df73b44).

It should have been reverted in Bug 1641291, which allowed
NSDISTMODE=copy to impact build manifests.  This is useful when
cross-compiling: this stops some symlinks within the object directory
itself, say from `dist/include` to an object directory.

# With LTO, object files are temporary, and are not kept around, which
# means there's no object file for dsymutil to do its job. Consequently,
# there is no debug info for LTOed compilation units.
# The macOS linker has however an option to explicitly keep those object
# files, which dsymutil will then find.

# files, and doesn't avoid conflicts from multiple linkers running at

# from the first linked binaries would be overwritten by those of the
# last linked binary. So we use a subdirectory containing the name of the
