System: FreeBSD lerbsd.lerctr.org 4.4-RC FreeBSD 4.4-RC #17: Sat Aug 18 17:22:20 CDT 2001 ler@lerbsd.lerctr.org:/usr/obj/usr/src/sys/LERBSD i386
>Description:
The cross-tools that are built use the *HOST* libc.a. Therefore certain tools
that are executed on the *TARGET* machine will possibly be linked with
inappropriate libraries.
The strip binary used during installworld is one of these, there may be others.
I've had a discussion with Marcel Moolenaar and John Baldwin on the
freebsd-stable list both recently and around the 4.3-RELEASE cycle.
This PR is to avoid the issue being lost.
>How-To-Repeat:
Build/Install world with /etc/make.conf having CPUTYPE=p3.
Update /etc/make.conf to change CPUTYPE=i486
make buildworld
NFS mount /usr/obj and /usr/src onto a 486
make installworld on the 486
watch strip die with SIGILL (signal #4) due to a P3 (cmova) instruction
in the strip binary.
>Fix:
Update build system to NOT include host libc.a in any tools that will be
executed on the target system.
