[Bug driver/38864] New: Incorrect interaction between --with-arch=native and -mARCH

$ ../trunk/configure --with-arch=native --disable-java-awt --without-x
--enable-__cxa_atexit --disable-libgomp --disable-static
--enable-languages=c,c++,java --disable-fixed-point --enable-checking=release
--with-gmp=/home/daney/mp --with-mpfr=/home/daney/mp --disable-libmudflap
--disable-multilib

As noted in these test results:

http://gcc.gnu.org/ml/gcc-testresults/2009-01/msg01307.html

We have FAIL: gcc.target/mips/dpaq_sa_l_w.c (test for excess errors)

Here is the log of the failure:

The native CPU is an R5000

My untested hypothesis is that configuring with --with-arch=native has
incorrect interaction with -m* from the gcc command line.
