net-misc/ices: fix build with clang/lld and upcoming clang-16

One configure test was broken with (any) clang/lld on multilib profiles
due to passing -L/usr/lib which led to underlinking wrt #740794.

For 16 it's the usual missing header, handled by adjusting the autoconf
test (revbumped in previous commit at same time for other compilers).
