ahh, looks like a problem in angstrom...  strace -f tells me:

[pid 19028] execve("/OE/angstrom-dev/staging/x86_64-linux/usr/bin/m4", ["/OE/angstrom-dev/staging/x86_64-"..., "/usr/share/bison/m4sugar/m4sugar"..., "-", "/usr/share/bison/yacc.c"], [/* 19 vars */]) = -1 ENOENT (No such file or directory)


so bison is trying to execute m4 from the path where it was on the host computer where bison was cross-compiled.. rather than /usr/bin/m4..

some symlink hackery gets me past this..
