[Bug bootstrap/32829] New: CVS bootstrap failure with as: unrecognised option -Qy

[brian dot sidebotham at gmail dot com]

A very old report from v2.97 seems very similar, but had no infomation about
the cause - see:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=2034

Bootstrapping gcc fails with the error:
/home/brian/public/gnu/arm-elf/install.unix/arm-elf/bin/as: unrecognised option
`-Qy`

Where ...arm-elf/bin/as is a current binutils cvs version just compiled

The configure line is:
../src/configure --target=arm-elf --enable-interwork --enable-multilib
--enable-languages=c --without-headers
--prefix=/home/brian/public/gnu/arm-elf/install.unix

The command that causes the error is:
gcc -c   -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE  -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition
-Wmissing-format-attribute -fno-common   -DHAVE_CONFIG_H -DGENERATOR_FILE -I.
-Ibuild -I../../gcc/gcc -I../../gcc/gcc/build -I../../gcc/gcc/../include
-I../../gcc/gcc/../libcpp/include  -I../../gcc/gcc/../libdecnumber
-I../../gcc/gcc/../libdecnumber/dpd -I../libdecnumber    -o build/genmodes.o
../../gcc/gcc/genmodes.c

The pre-processed file is available at http://www.valvers.com/genmodes.i

The output of adding -v -save-temps to the command is:
brian@dannii:~/public/gnu/gcc/build.unix/gcc$ gcc -v -save-temps -c   -g -O2
-DIN_GCC -DCROSS_DIRECTORY_STRUCTURE  -W -Wall -Wwrite-strings
