Yes, you should avoid cross-emerging glibc to your 'sysroot', or
/usr/arm-softfloat-linux-gnueabi, if at all possible.
On a related note, if you're using that toolchain for the FR, then you
can squeeze out a few bytes of space, and squeeze in a few cycles of
performance if you set CFLAGS="-O2 -mcpu=arm920t -fomit-frame-pointer
-pipe" ... you'll loose the frame pointer for debugging purposes, but
compiling specifically for the arm920t core will certainly improve
overall performance and decrease binary size.
