More ash fixes

[Pavel Roskin]

Hello!

Here are more fixes related to ash.

ChangeLog:
        * autoheader.sh: Don't check status of variable assignment -
        it's undefined in ash 0.2.
        * autoreconf.sh: Likewise.
        * autoupdate.sh: Likewise.
        * autoconf.sh: Likewise. Eliminated command substitution
        inside variable expansion - ash 0.2 coredumps on it.

Regards,
Pavel Roskin
