[PATCH] Fix buildcheck.sh on Solaris

The /bin/sh on Solaris does not seem to support the
$(which glibtool...) semantics. Furthermore, converting it to
`which glibtool libtool...` on Solaris does not work either as
which does not send "not found" errors to stderr but to stdout.
This results in $libtool set to "glibtool not found" even when
libtool is in the path.

So, the following must be applied to get buildcheck.sh to
work on Solaris. -- justin

----
buildcheck.sh: Make libtool detection work with Solaris and /bin/sh.
