world's toolchain & CPUTYPE

Yesterday I hit the following problem:
- was given an Athlon XP machine with a fresh CURRENT built with
- used it to build a fresh RELENG_6 world with no customizations
at all -- __MAKE_CONF=/dev/null;
- tried to install the world over NFS on an old Pentium machine
with some 5.3-BETA;
- "make installkernel" failed instantly because install(1) died on
signal 4, illegal instruction.
Quick investigation showed that the world was built using generic
i386 code, as expected, but its toolchain was linked against the
builder system libs contaminated by Athlon-specific code. It was
sufficient to rebuild and reinstall all libs on the builder machine
with no particular CPUTYPE set and then to rebuild the world's
toolchain again to make the latter run well on the Pentium.
I used to be under impression that a world's toolchain should be
fairly independent from the builder system. However, this case
showed that it wasn't quite true. Is it a known issue, or am I
missing a key point? Thanks!
