makepkg: CHOST unbound variable

Hi,
I want to build https://aur.archlinux.org/packages/gcc49

But when I makepkg -si, I get this:

/home/basti/gcc49/PKGBUILD: line 149: CHOST: unbound variable
/usr/bin/makepkg: line 131: logpipe: unbound variable

the PKGBUILD:

the error points to 149, which is the closing bracket. Inside $CHOST is used.
      --build="${CHOST}"

my makepkg.conf sets CHOST. I do not understand, why the error occurs.
