De-POSIXify the shell usage in gen-avr-lib-tree.sh, since
Solaris' /bin/sh is not POSIX-aware.  For the remaining tools,
their POSIXish variants can be chosen by prepending the PATH with
/usr/xpg4/bin (doesn't harm for non-Solaris systems), but as for
the shell this script is running under, the only other option
were to let autoconf detect it, which is a bit of overkill.

Fixed a brain fart.  Function to compute length of month did not match prototype.
