libgcc for Debian armel with qemu-arm-static
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org

libgcc2.i from xgcc
Same source compiled fine with amd64 native tools.
GCC tested are:
1. xgcc (GCC) 7.0.0 20161105 (experimental) (github: trunk@241870)
2. gcc (Debian 6.2.0-11) 6.2.0 20161103
System:
/usr/bin/qemu-arm-static
Debian sid chroot
Configure:
1. ../configure
That resulted to config.status including
--enable-languages=c,c++,fortran,lto,objc
