A strace of

	$ .../host/bin/arm-linux-gcc -v

shows

	24399 execve(".../host/opt/ext-toolchain/bin/arm-linux-gcc.br_real", ["/home/seiderer/Work/Buildroot/bu"..., "--sysroot", "/.../bu"..., "-mabi=aapcs-linux", "-mfpu=vfp", "-marm", "-mfloat-abi=hard", "-mcpu=arm1176jzf-s", "-Wl,-z,relro", "-v"], 0x7ffca405b940 /* 93 vars */) = 0


This one works:

	$ .../host/opt/ext-toolchain/bin/arm-linux-gcc.br_real --sysroot bla -mabi=aapcs-linux -mfpu=vfp -marm -mfloat-abi=hard -mcpu=arm1176jzf-s  -v

This one fails:

	$ .../host/opt/ext-toolchain/bin/arm-linux-gcc.br_real --sysroot bla -mabi=aapcs-linux -mfpu=vfp -marm -mfloat-abi=hard -mcpu=arm1176jzf-s -Wl,-z,relro -v

Peter
