libpcre2: Fix linking with LLD linker

version scripts are at odds with LLD at times and its strict about undefined symbols
even though they will be provided by c startup files.

Fixes
| riscv64-yoe-linux-ld.lld: error: version script assignment of 'local' to symbol '_fini' failed: symbol not defined
| riscv64-yoe-linux-ld.lld: error: version script assignment of 'local' to symbol '_init' failed: symbol not defined
| riscv64-yoe-linux-clang: error: linker command failed with exit code 1 (use -v to see invocation)
| make[1]: *** [Makefile:1948: libpcre2-32.la] Error 1
