Well may be it starts to become out-of-topics here in U-Boot list, but just one more thing:
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 macro cc-option "by hand" (so without $CFLAGS) in a bash shell and I got the same results as above, i.e. the check for option -mapcs-32 fails but the compiler support it and indeed the compilation works fine! May be a bug?
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 \ > /dev/null 2>&1; then echo "$1"; else echo "$2"; fi;
You could look for bug in the shell as well
