editors/vim several problems

[[LoN]Kamikaze]

Problem #1)
'make -j' breaks editors/vim already in the configure phase:

GUI_INC_LOC="" GUI_LIB_LOC=""  CC="cc" CPPFLAGS="" CFLAGS="-O2 -fno-strict-aliasing -pipe -march=pentium-m"  LDFLAGS=""  srcdir="."  ./configure --enable-gui=gtk --with-gtk-prefix=/usr/X11R6             --enable-multibyte --enable-fontenable-xim        --with-features=big        --prefix=/usr/local --with-tlib=termlib   
cp config.mk.dist auto/config.mk
rm -f auto/config.status auto/config.cache config.log auto/config.log
make: don't know how to make ./auto/osdef.h. Stop
*** Error code 2

updating cache auto/config.cache

config.status: creating auto/config.mk

1 error
*** Error code 2


Problem #2)
Vim does not honour CC and ignores things like 'CC= distcc cc'.
