I don't think it is possible to fix this in the FE.

Output of failing compilation (with -v -save-temps) and related files

I am trying to cross-compile latest GCC-4.9.1 to be run native on an arm board.
I am using the cross compiler from board manufacturer (Synology) on a Debian
GNU/Linux system.

I am using a script to compile so results are completely reproducible.

Cross-compiler is available at:
http://sourceforge.net/projects/dsgpl/files/DSM%204.2%20Tool%20Chains/Marvell%2088F628x%20Linux%202.6.32/gcc421_glibc25_88f6281-GPL.tgz/download
NOTE: this compiler has a cross-flex that confuses build, I had to remove it
from installation directory (/usr/local/arm-none-linux-gnueabi/bin)

I assume You know where to find the other referenced archives ;)

I will try to build a cross-gcc targeted to my board and then cross-compile a
native-gcc with that. I will post here results.
