I tried to get (and use) libm-no68881 (or whatever its name is).

The problem seems to be more complex than that because of the programs
in /bin, only ps is linked with libm.

I tried to install the 68881-less libm on my Mac IIcx running NetBSD
1.2_BETA and then build all the programs in /bin. No success: when
transferring both the new /bin programs and libm.so to the PB520, I still
get the illegal instruction errors.

I even tried to compile with gcc -msoft-float, but then the compiler
generates calls to functions that I don't have.

A funny observation: the echo command seems to work with no parameters
and when called as 'echo *', but not when called with a single string
parameter 'echo "something"'.

Any advice and suggestions are welcomed
