No worries. Here's what I did to actually reproduce the issue (just to provide 
more data):

- Install 8.0-RELEASE amd64 with minimal from sysinstall.
- pkg_add -r subversion vim-lite
- cd /usr/src && svn co svn://svn.freebsd.org/base/head .
- Add the following bits to make.conf:

CFLAGS+=                -O2 -fno-strict-aliasing
CXXFLAGS+=      -O2 -fno-strict-aliasing

CFLAGS+=                -save-temps
CXXFLAGS+=      -save-temps

CPUTYPE=                nocona

- make -j4 buildworld && make -j4 buildkernel # bombed at ncurses with termcap 
error
- make -j2 buildworld && make -j4 buildkernel # bombed at ncurses with termcap 
error
- make buildworld buildkernel # bombed at ncurses with termcap error
- make kernel-toolchain # passed
- make buildworld # bombed at rescue/rescue
- make -C release/release depend # bombed with lzma
- make -C lib/lzma depend installincludes # bombed because /usr/include/lzma 
was missing
- mkdir -p /usr/include/lzma
- make -C lib/lzma installincludes # passed
- make -C rescue/rescue depend all # still bombed ; set WITHOUT_RESCUE in 
src.conf
- make buildworld buildkernel # passed

-save-temps seems to unroot some race conditions in the GNU toolchain as it 
barfed a lot with -j greater than 1 with some ASM related errors, but for 
whatever reason binutils was getting cranky and failing a lot with missing 
ncurses symbols, which kind of got me into this spiraling build failure cycle.

Hopefully that helps better describe what I did to get to the failing state. As 
I said earlier, I'll try to reproduce and characterize the situation further 
before filing a bug report.

Thanks,
