Update: Using the above line in mpg123/Makefile (with dream changed to
linux-sh for consistency), I built mpg123 and executed it on the Dreamcast =
...
no problems whatsoever.

You must have a snag in your toolchain somewhere.  I'm using (all patched
with the latest patchset from ftp.m17n.org/pub/super-h/testing/) binutils
2.11.2, GCC 3.0.3, and glibc 2.2.4.  This was executed under the busybox
shell (the sh-like one) under kernel 2.4.16.
