>Description:
Trying to build /usr/ports/lang/lua with the following command results in a compilation failure:

env TARGET_ARCH=i386 make

The error message is:

cc: i386: No such file or directory

This is the identical problem documented in all of the following problem reports:

http://www.freebsd.org/cgi/query-pr.cgi?pr=147853
http://www.freebsd.org/cgi/query-pr.cgi?pr=151224
http://www.freebsd.org/cgi/query-pr.cgi?pr=156607

In addition to fixing the problem for lang/lua, please, please, please assign someone knowledgeable about this problem to the task of searching the entire ports collection for all instances of this same bug, rather than hoping random end users will eventually discover and report them all one at a time. It is simply wrong to waste end user time that way!

>How-To-Repeat:
env TARGET_ARCH=i386 make
>Fix:
The attached patch applied to /usr/ports/lang/lua/makefile fixed the problem for me, just as similar patches worked for problem reports ports/147853, ports/151224, and ports/156607.
