skip checking categorization of libperl symbols for LTO builds
For LTO builds with gcc and clang the PL_no_mem symbol as listed bynm is flagged as "D" (writable data) and "T" (text, aka code)respectively.Looking at the final generated executable PL_no_mem does end up inthe .rodata (read only data) section, so it might be worth adding aseparate test for that.Fixes#20518
