wiringpi: Fix linking problem

Browse Source 
[github issue #105: wiringpi library is not linked correctly]

Incorrect order of compiler flags causing the libwiringpi.so library
to not have the required linking dependencies. The cross-compilation
patch needed to be reworked in order to fix this problem.

Fixes #105
