[Bug bootstrap/25672] New: wrong cflags passed to ./xgcc

["pluto at agmk dot net" <gcc-bugzilla at gcc dot gnu dot org>]

I'm configuring gcc with:

./configure --prefix=/usr --infodir=/usr/share/info --mandir=/usr/share/man
--bindir=/usr/bin --libdir=/usr/lib --libexecdir=/usr/lib --disable-shared
--disable-threads --enable-languages=c,c++ --enable-c99 --enable-long-long
--disable-nls --with-gnu-as --with-gnu-ld --with-demangler-in-ld
--with-system-zlib --enable-multilib
--with-headers=/home/users/builder/rpm/BUILD/gcc-4.1-20051230/fake-root/usr/include
--without-x
--target=ppc64-pld-linux
--host=i686-pld-linux
--build=i686-pld-linux
CFLAGS=-O2 -march=i686 -mtune=pentium4 -ggdb
CXXFLAGS=-O2 -march=i686 -mtune=pentium4 -ggdb
TEXCONFIG=false

it worked fine with gcc-4.0.2.
in 4.1 ./xgcc gets wrong cflags (from host).
