pkgbuild

The umn.dl.sourceforge.net mirror is currently down and a pkgbuild running
on a spec file pointing to this mirror takes too long to timeout.

The root cause is that wget is invoked with -T 60 in the function
wget_source() in pkgtool.pl. "-T" just specifies the timeout. wget also has
a notion of "retry", where it retries a URL multiple times (by default 20)
with the given timeout. So the total time spent waiting on the unresponsive
server turns out to be 20 x 60 seconds = 20 minutes. Way too long !

Solution:

pkgbuild should limit wget to a single retry with the --tries=1 (-t 1)
option.
