#950 configure errors / host - target

[g.fischer]

configure is messing up vars completely. it takes my
cflags as host type:

configure: warning: CC=c99: invalid host type
configure: warning: CFLAGS=-O3 -mips4 -lfastm -lm
-TARG:platform=IP27:proc=r12000
-OPT:Olimit=0:roundoff=3:IEEE_arithmetic=3: invalid
host type
configure: error: can only configure for one host and
one target at a time
configure: error: /bin/sh './configure' failed for cvsunix
