I don't think it is OT as long as the config.mk files are part of
U-Boot and they don't work as expected (unless the bug is definitely
in a different tool).

I tried the below file (with CC set to your compiler) and it works as
expected for me (called with the two options as arguments), choosing
-mapcs-32 (but it's a 3.4.0 compiler):

  #!/bin/sh

  CC=arm-linux-gcc

  if $CC $1 -S -o /dev/null -xc /dev/null \

You could look for bug in the shell as well
