My arm cross is self-built, with configure options mirroring a native fedora
arm gcc:

Target: armv7l-linux-gnueabihf
Configured with: ../comb/configure --with-sysroot
--prefix=/home/rth/work/gcc/run-cross --enable-languages=c,c++,lto
--target=armv7l-linux-gnueabihf --with-system-zlib --enable-__cxa_atexit
--enable-gnu-unique-object --enable-linker-build-id
--with-linker-hash-style=gnu --enable-initfini-array --with-cpu=cortex-a15
--with-float=hard --with-fpu=neon-vfpv4 --with-abi=aapcs-linux
Thread model: posix
gcc version 7.0.0 20161220 (experimental) [master revision
