>Description:
Build world using WITH_BSD_GREP=yes and with WITHOUT_GNU_COMPAT defined so that bsdgrep does not use the gnu regex library.  Install the resulting binary and then make buildworld again, and the buildworld fails at usr.bin/kdump.  The invocations of grep in the mksubr script don't generate the same results without the gnu library as they do with the library.  

This expression generates an error message:

egrep '^#[[:space:]]*define[[:space:]]+SHM_[A-Z]+[[:space:]]+[0-9]{6}+[[:space:]]*' /usr/obj/arm.arm/usr/src/tmp/usr/include/sys/shm.h
egrep: repetition-operator operand invalid

And this expression incorrectly fails to find any matching lines:

+ egrep '^#[[:space:]]*define[[:space:]]+PF_[[:alnum:]]+[[:space:]]+[[:space:]]*' /usr/obj/arm.arm/usr/src/tmp/usr/include/sys/socket.h

 Addition info... the buildworld that generated the failing bsdgrep was
 done with these options:
 
 -DMALLOC_PRODUCTION 
 WITHOUT_BIND=yes 
 WITHOUT_CLANG=yes 
 WITHOUT_GAMES=yes 
 WITHOUT_GNU=yes 
 WITHOUT_GNU_COMPAT=yes 
 WITHOUT_GNU_SUPPORT=yes 
 WITHOUT_HTML=yes 
 WITHOUT_I4B=yes 
 WITHOUT_NLS=yes 
 WITHOUT_OBJC=yes 
 WITHOUT_SHAREDOCS=yes 
 WITHOUT_KERBEROS=true 
 WITHOUT_LPR=yes 
 WITHOUT_MAN=yes 
 WITHOUT_PROFILE=yes 
 WITHOUT_SENDMAIL=yes 
 WITH_BSD_GREP=yes 
 
 I tried both WITH_NLS and WITHOUT_NLS, same error either way.  I didn't
 try toggling other options (doesn't seem like any others should matter).
