gmake-4.2.1 ignores assignment of ARCH on FreeBSD

[Yuri]

I found this problem on this project: 
http://zimpl.zib.de/download/zimpl-3.3.4.tgz

Makefile there assigns ARCH after shell/sed substitutions, and this line 
has no effect at all in gmake version from the FreeBSD port.

I have to assume that it worked on Linux when it was written.


Is this a feature that it ignores assignments, or a bug?

Or, maybe, it is a discrepancy in the FreeBSD port's gmake.


I saw other strange discrepancies in gmake on FreeBSD on other projects.
