[Slackbuilds-users] libpng-legacy12.SlackBuild patch for MultiLib

[Konrad J Hambrick]

B. Watson / Willy --

I am running Slackware64 14.2 + Multilib and in order to make TeamViewer
work, I had to install a 32-bit version of libpng-legacy12

I also went ahead and installed the 64 bit version as well and that caused
a 'dupe package' error in my `find-sbo-updates.sh` script.

As a work-around, and more-or-less in keeping with Alien Bob's convention
of appending -compat32 to the $PRGNAM for his 32-bit versions of standard
Slackware Packages, I've patched libpng-legacy12.SlackBuild to append
'-32bit' to the $PRGNAM when building an ARCH=i486 Package on a `uname -m`
= X86_64 machine.

Not sure this is in keeping with the SBo Rules but it works for me :)

Thanks for all your SBo goodies !
