Port new fingerprinting scheme to clang + LTO
* lib-src/make-fingerprint.c (main): Don't consider multiple
instances of the fingerprint to be an error, as this can
happen with clang and -flto. Instead, replace all instances
of the fingerprint. There is a tiny chance that this will
silently corrupt the Emacs executable.
This patch suggests that we should go back to fingerprinting
the inputs to the linker instead of its output, as the new
fingerprinting scheme is unnecessarily complicated and this
complexity reduces reliability. The old scheme (i.e., before
commit 2019-05-14T23:31:24Z!eggert@cs.ucla.edu) was simpler
and more portable and good enough, and it's looking like it
would be less trouble in practice than the new scheme.
