Hi Oliver,
The problem is that the ${.CURDIR:M/usr/src/*} expressions are wrong,
they will not match when you are *exactly* in /usr/src or in /usr/obj.
So for any operations in the "root" of your source checkout, or of your
object directory, CC will still be 'cc', and unexpected things will
happen.
It is better to use:
.if ${.CURDIR:M/usr/src*} || ${.CURDIR:M/usr/obj*} || ${.CURDIR:M/sys*}
or if you want to be strict:
.if ${.CURDIR:M/usr/src} || ${.CURDIR:M/usr/src/*} || ${.CURDIR:M/usr/obj} || ${.CURDIR:M/usr/obj/*} || ${.CURDIR:M/sys} || ${.CURDIR:M/sys/*}
It is similar to a problem another user reported on freebsd-stable
(though he got a weird linker error instead):
http://lists.freebsd.org/pipermail/freebsd-stable/2011-December/065172.html
After some analysis, it turned out he had the same problem in his
make.conf:
