It seems like the process to install files isn't preserving mtime which
reduces the effectiveness of other build systems which work based on mtime
for computing what needs to be compiled. Specifically, one case, ft2build.h
seems to get copied without preserving mtime:
/usr/bin/install -c -m 644

The main issue, as demonstrated, is that the mtime of the file is not
preserved. This means that build tools that depend on mtime (e.g. make)
fail to work as efficiently as possible as it appears that the file has
