I checked out the grep 'git' repository, reverted the bootstrap.conf
change, did
  $ ./bootstrap
and got:

  ...
  ./bootstrap: autoconf --force ...
  configure.ac:27: error: possibly undefined macro: AC_DEFINE
        If this token and others are legitimate, please use m4_pattern_allow.
        See the Autoconf documentation.

The generated configure file indeed contains

  # support for pcre
  PKG_PROG_PKG_CONFIG
  if test x"$testpcre" = x"yes"; then
    PKG_CHECK_MODULES(PCRE, libpcre,
            AC_DEFINE([HAVE_LIBPCRE], 1,
              [Define to 1 if you have the `pcre' library (-lpcre).])
             CPPFLAGS="$CPPFLAGS $PCRE_CFLAGS",
            :)
  fi

Apparently a definition of the macros PKG_PROG_PKG_CONFIG and PKG_CHECK_MODULES
is missing from the grep/m4/ directory. Please add these macros there;
pkg-config is not a standard development tool present on every developer's
machine.
