Arch Linux

Summary and Info:
makepkg runs `mkdir pkg` twice, failing the second time, since it's already there. This leads to:
```
==> Entering fakeroot environment...
mkdir: cannot create directory ‘/home/despairblue/git/synergy/pkg/’: File exists
/usr/bin/fakeroot: line 181: 3529 User defined signal 1 FAKEROOTKEY=$FAKEROOTKEY LD_LIBRARY_PATH="$PATHS" LD_PRELOAD="$LIB" "$@"
```

Steps to Reproduce:
Use that PKGBUILD: https://gist.github.com/despairblue/21b7cde32497c7e151d5
I also put `set -x` on top of the PKGBUILD and included the log. When you search backwards for `mkdir` it becomes apparent what happens.
