For newlib, there should be various libc.a and libm.a files in the build
directory.

Use find to locate them: find . -name libc.a

And use "nm" to find out if the symbol is there.

sparc-rtems6-nm .../libc.a

You can save that output or pipe it to less.

Note: paths need to be adjusted to the files.
