mvme5500, rtems-4.9.0: undefined reference to `cos'

[rtwas]

Hello,

Despite having "-lm" clearly visible in the command-line trig functions go
unresolved at link time.

I took "examples-4.9.0/psx_example/test.c", removed everything but the 
directives. I made up a
dummy pointer to *something* so the compiler wouldn't try to optimize 
out the call to "cos()".

I did this test after seeing this problem in a much more substantial build.

Help appreciated,

Thanks.

Robert W.
