cross-platform with fatal error: 'linux/i2c.h' file not found

[rurban]

doesnt look that cross-platform to me. these errors are on macOS, but FreeRTOS or baremetal would have the same problems.

../../include/SPI.h:9:10: fatal error: 'linux/spi/spidev.h' file not found #include <linux/spi/spidev.h> ../../include/I2C.h:13:10: fatal error: 'linux/i2c.h' file not found #include <linux/i2c.h>

looks like linux-only to me.
