On Alpine Linux 3.14 the build works fine, but there is one test failure:

FAIL: contrib/gdiffmk/tests/

Find attached the log file. The cause is apparently that the 'diff' program
on this platform is not GNU diff, but diff from BusyBox. See:

$ diff --version
diff: unrecognized option: version
BusyBox v1.33.1 () multi-call binary.

Usage: diff [-abBdiNqrTstw] [-L LABEL] [-S FILE] [-U LINES] FILE1 FILE2

Compare files line by line and output the differences between them.
This implementation supports unified diffs only.

        -a      Treat all files as text
        -b      Ignore changes in the amount of whitespace
        -B      Ignore changes whose lines are all blank
        -d      Try hard to find a smaller set of changes
        -i      Ignore case differences
        -L      Use LABEL instead of the filename in the unified header
        -N      Treat absent files as empty
        -q      Output only whether files differ
        -r      Recurse
        --no-dereference Don't follow symlinks
        -S      Start with FILE when comparing directories
        -T      Make tabs line up by prefixing a tab when necessary
        -s      Report when two files are the same
        -t      Expand tabs to spaces in output
        -U      Output LINES lines of context
        -w      Ignore all whitespace
