I've just updated to 'current' and unfortunately the builf is failing.
Something must have changed because this has all worked many times before.

I use the following script (not all of which is probably required):

#!/bin/sh
exec 2>&1
base=`(cd ..;/bin/pwd)`
DESTDIR=$base/dest
RELEASEDIR=$base/release
objdir=$base/obj
export DESTDIR RELEASEDIR
build.sh -d -u -U -D $DESTDIR -O $objdir "$@"

usually invoked as 'build | tee log'

The first fail was missing 'string_to_flags' when linking xinstall.
Some makefile 'magic' is involved in picking this up...

I then did 'rm -rf $obj/tools' and reran build.sh.
This time it didn't recreate $obj/tools and started dumping all the
object files in the source directory tree.

Cleaned up...
Created $obj/tools by hand and tried again
This time the link of xinstall fails because -lnbcompat cannot be found.
A little digging shows that it exists in the $src tree instead of the
$obj one!

The relevant bit of the log goes:
cc -O  -I. -I./include -I/oldroot/usr/bsd-current/src/tools/compat -DHAVE_CONFIG
_H  -D_FILE_OFFSET_BITS=64 -D__DBINTERFACE_PRIVATE -c -o rec_utils.lo.o /oldroot
/usr/bsd-current/src/tools/compat/../../lib/libc/db/recno/rec_utils.c
mv rec_utils.lo.o rec_utils.lo
rm -f /oldroot/usr/bsd-current/src/tools/compat/libnbcompat.a
ar cq /oldroot/usr/bsd-current/src/tools/compat/libnbcompat.a basename.lo ...

The .lo files are all in $obj, but for some reason the .a file
is put in the source tree.

With an empty 'tools' I also got the following:
obj ===> usr.bin/vacation
obj ===> usr.bin/vgrind
