This seems to have been just copied-and-pasted from some other header checks. But our C code is entirely unprepared to support such a header name, so it's only wasting cycles to look for it. If we did need to support it, some #ifdefs would be required. (A quick trawl at codesearch.debian.net finds some packages that reference lz4/lz4.h; but they use *only* that spelling, and appear to be intending to reference their own copy rather than a system-level installation of liblz4. There's no evidence of freestanding installations that require this spelling.) Discussion: https://postgr.es/m/457962.1616362509@sss.pgh.pa.us
