Bug 274106: java/openjdk8: fix build with lld 17
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274106



--- Description ---
Building java/openjdk8 with lld 17 results in the following link error:

Making SA debugger back-end...
ld: error: version script assignment of 'SUNWprivate_1.1' to symbol 'ps_getpid'
failed: symbol not defined
ld: error: version script assignment of 'SUNWprivate_1.1' to symbol
'ps_lcontinue' failed: symbol not defined
ld: error: version script assignment of 'SUNWprivate_1.1' to symbol
'ps_lgetxmmregs' failed: symbol not defined
ld: error: version script assignment of 'SUNWprivate_1.1' to symbol
'ps_lsetxmmregs' failed: symbol not defined
cc: error: linker command failed with exit code 1 (use -v to see invocation)

This is because lld 17 defaults to errors when undefined symbols are referenced
in linker version scripts. Since there are many of these in openjdk 8, suppress
the errors by adding -Wl,--undefined-version to the --with-extra-ldflags
configure option.
