[PATCH] picolibc: Use %:find-file for both test and access to picolibc.ld

If the gcc driver and linker don't agree on what the search path for
linker scripts is, then the driver may discover a file that
the linker won't end up using. This results in linking failures
when applications don't specific an explicit linker script.

Fix this by duplicating the call to %:find-file for both
test and in the parameter passed to the linker.

gcc/
	* config/picolibc-spec.h (LIBC_LINK_SPEC): Use find-file for test
	and access to picolibc.ld.
