shave: hack around the configure ld check for make distcheck.

configure calls $(CC) -print-prog-name=ld to get the binary for the linker.
The shave script prints " CC \nld" which can't be parsed by configure,
resulting in a fatal error.

This patch special-cases -print-prog-name and passes it though directly
without any additional output.
