Define MEGA_SOFT_SPI to use software SPI on Mega Arduinos. Pins used are SS 10, MOSI 11, MISO 12, and SCK 13.

MEGA_SOFT_SPI allows an unmodified Adafruit GPS Shield to be used on Mega Arduinos. Software SPI works well with GPS Shield V1.1 but many SD cards will fail with GPS Shield V1.0. SPI Slave Select pin
