I did some quick googling on this point. We seem not to be the only
project having linking issues on Alpine, and yet it does support
LD_LIBRARY_PATH according to some fairly authoritative-looking pages, eg
https://www.musl-libc.org/doc/1.0.0/manual.html
I suspect the situation is similar to macOS, ie there is some limitation
somewhere on whether LD_LIBRARY_PATH gets passed through. If memory
serves, the problem on SIP-enabled Mac is that DYLD_LIBRARY_PATH is
cleared upon invoking bash, so that we lose it anywhere that "make"
invokes a shell to run a subprogram. (Hmm ... I wonder whether ninja
uses the shell ...) I don't personally care at all about Alpine, but
maybe somebody who does could dig a little harder and characterize
the problem there better.
