--- Comment #1 from Pauli <suokkos at gmail dot com> ---
Sorry. Error in original report:
gcc (Debian 6.2.0-11) 6.2.0 20161103

with command:
gcc -isystem /usr/local/armv7l-unknown-linux-gnueabi/include -isystem
/usr/local/armv7l-unknown-linux-gnueabi/sys-include    -g -O2 -O2  -g -O2
-DIN_GCC    -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual
-Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition  -isystem
./include   -fPIC -fno-inline -g -DIN_LIBGCC2 -fbuilding-libgcc
-fno-stack-protector   -fPIC -fno-inline -I. -I. -I../.././gcc
-I../../../libgcc -I../../../libgcc/. -I../../../libgcc/../gcc
-I../../../libgcc/../include    -o _muldi3.o -MT _muldi3.o -MD -MP -MF
_muldi3.dep -DL_muldi3 -c ../../../libgcc/libgcc2.c -fvisibility=hidden
-DHIDE_EXPORTS

works fine. I forgot that actual compile job is separate process when testing
system gcc.

On amd64 host:
/home/coren/project/gcc/buildamd64/./gcc/xgcc
-B/home/coren/project/gcc/buildamd64/./gcc/ -isystem
/usr/local/armv7l-unknown-linux-gnueabi/include -isystem
/usr/local/armv7l-unknown-linux-gnueabi/sys-include    -g -O2 -O2  -g -O2
-DIN_GCC    -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual
-Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition  -isystem
./include   -fPIC -fno-inline -g -DIN_LIBGCC2 -fbuilding-libgcc
-fno-stack-protector   -fPIC -fno-inline -I. -I. -I../.././gcc
-I../../../libgcc -I../../../libgcc/. -I../../../libgcc/../gcc
-I../../../libgcc/../include    -o _muldi3.o -MT _muldi3.o -MD -MP -MF
_muldi3.dep -DL_muldi3 -c
/home/coren/project/gcc/buildarmel/armv7l-unknown-linux-gnueabi/libgcc/libgcc2.i
-fvisibility=hidden -DHIDE_EXPORTS

works fine.


Too bad compile cycle for armel is very long (about 30 hours) making it very
annoying that cc1 doesn't have debug symbols.
