commit 576960c1cf5c6fe4c4df7ce08a3cad3a24dedb13
Author: Xi Ruoyao <xry111@xry111.site>
Date:   Fri Jun 24 17:36:40 2022 +0800

    config: use $EGREP instead of egrep
    
    egrep has been deprecated in favor of grep -E for a long time, and the
    next GNU grep release (3.8 or 4.0) will print a warning if egrep is used.
    Unfortunately, old hosts with non-GNU grep may lack the support for -E
    option.  Use AC_PROG_EGREP and $EGREP variable so we'll work fine on
    both old and new platforms.
    
    ChangeLog:
    
            * configure.ac: Call AC_PROG_EGREP, and use $EGREP instead of
            egrep.
            * config.rpath: Use $EGREP instead of egrep.
            * configure: Regenerate.
    
    config/ChangeLog:
    
            * lib-ld.m4 (AC_LIB_PROG_LD_GNU): Call AC_PROG_EGREP, and use
            $EGREP instead of egrep.
            (acl_cv_path_LD): Likewise.
            * lib-link.m4 (AC_LIB_RPATH): Call AC_PROG_EGREP, and pass
            $EGREP to config.rpath.
    
    gcc/ChangeLog:
    
            * configure: Regenerate.
