vasilito 45696b918b git: re-port git.patch onto 2.55.0 
The patch was written against git 2.13.1 (2017) while the recipe fetches
2.55.0 — eight years of drift, seven of eight files rejecting. Rebased by
applying what still fit, hand-porting every reject against the current
source, and regenerating the whole patch from a pristine-vs-ported diff so
it is a coherent 2.55.0 patch rather than a 2.13 patch with fixups.

Per file, preserving the original Redox intent:
  compat/bswap.h      <machine/endian.h> for ntohl/htonl
  compat/terminal.c   __redox__ git_terminal_prompt branch; the file was
                      restructured, so it now precedes the generic #else
  configure           NO_IPV6=YesPlease
  daemon.c            logreport is a switch over LOG_DESTINATION_* in
                      2.55.0; guard the syslog arm and openlog instead of
                      the old if/else
  git-compat-util.h   SIG_DFL/SIG_IGN/SIG_ERR fallbacks
  Makefile            EXTLIBS=-lnghttp2; drop the three hardlink fallbacks
  run-command.c       dup_devnull is gone in 2.55.0; the four /dev/null
                      opens it replaced now use DEV_NULL directly
  setup.c             sanitize_stdfds uses xopen/xdup, which die
                      internally, so the old die_errno hunk is obsolete

Applies at --fuzz=0 with zero rejects across all eight files.

Also ac_cv_iconv_omits_bom=no: the 'iconv omits bom for utf-16 and
utf-32' probe is a RUN test and cannot execute while cross compiling.
Same mechanism as the neighbouring ac_cv_fread_reads_directories and
ac_cv_snprintf_returns_bogus entries.

One trap worth recording: a blanket '*.orig' cleanup before regenerating
the diff silently deleted t/t4256/1/mailinfo.c.orig, a real git test
fixture, which would have shipped as a deletion in the patch. Restored.
