lsof: don't use host toolchain to determine target libc

The lsof Configure script builds a test program using the host toolchain to
test whether glibc is used. This test is broken in cross compilation
environment. Set LINUX_CLIB to avoid the test. This should give the correct
result even for non glibc toolchains, since all libc variants we support have
the netinet/tcp.h header.
