OHOS: Add linker configuration files

Since commit 1e35163ae8, the WHOLE_ARCHIVE feature is defined in the
linker configuration modules. OHOS had no such files, so
$<LINK_LIBRARY:WHOLE_ARCHIVE,...> failed there.

Add forwarding files to the Linux linker configuration, as done for
Android in commit d2997ab601. Unlike Android, fall back to LLD when the
linker cannot be identified, because the OHOS SDK toolchain file links
with -fuse-ld=lld.
