ALL: make configure work under FreeBSD
|Reported by:||sev-||Owned by:||SF/ender|
In FreeBSD sdl-config script for SDL-1.2 is named as
sdl11-config. (sdl-config is used with SDL-1.0).
There was a bug in find_sdlconfig() subroutine in gile
configure, and sice PATH settings wasn't taken in
account, it always failed to find proper sdl-config file.
This patch fixes it.
