Subject: [PATCH] arch.sh: Syntax error fix

Script failed for me with following error
PX4-Autopilot/Tools/setup/arch.sh: line 159: syntax error near unexpected token `else'
PX4-Autopilot/Tools/setup/arch.sh: line 159: `			else'
Seems like there is nothing to do in case of positive if case.
Changed code should maintain logic
