- AC_PATH_PROG(SH,bash sh)
  this only checks whether bash exists in ${PATH}, not sh
  AC_PATH_PROGS() is suppose to check for each program in the blank-separated list,
  and there is no bash in the FreeBSD base system.

- AC_CHECK_TARGET_TOOLS(OBJDUMP,gobjdump objdump)
  /usr/bin/objdump (the GNU version) was removed from the FreeBSD base system
  https://cgit.freebsd.org/src/commit/?id=0ad202f312f6da4f2774ecb7a3f3c2a05b3dde5f
  add llvm-objdump to the list for ${OBJDUMP}.

- AC_SEARCH_LIBS(MD5Init,md,AC_DEFINE([HAVE_LIBMD5], [1], [Define to 1 if you have the md5 library]),)
  PR 273735: fails to build if www/libwww installed
  Remove md5 and only searches for md here to avoid linking with lib/libmd5.*
  installed by www/libwww.
