mkbltnmlst.sh sources directories.

[Tanaka Akira <akr@xxxxxxxxxxx>]

mkbltnmlst.sh sources directories as:

make[1]: Entering directory `/home/akr/src/zsh/cvs/zsh/Src'
srcdir='.' MODBINS='modules-bltin' \
XMODCF='./xmods.conf' /bin/sh ./mkbltnmlst.sh bltinmods.list
./mkbltnmlst.sh: .: ./../: is a directory
...

Note that this result is on linux.  On Solaris 7, /bin/sh actualy
sources a directory and generates messy errors:

srcdir='.' MODBINS='modules-bltin' \
XMODCF='./xmods.conf' /bin/sh ./mkbltnmlst.sh bltinmods.list
./mkbltnmlst.sh: ^Dku^L^A.^A^F^[^L^B..^Dzl^L^CCVS^Dkv^X^MChangeLog.3.0^Dkw^T: not found
./mkbltnmlst.sh: .cvsignore^Dkx^T: not found
...

Is this fix correct?
