Pass a build id of "none" to the linker to suppress a warning about the
build id being ignored:
/usr/bin/ld: warning: .note.gnu.build-id section discarded, --build-id
ignored.

Thanks. Got idea from this that the ELF format used in the test could
be further refined with something like ".note.x86.tcs", which would
contain the start offset and size of the TCS list.
