Description
Hi i narrowed down, why display drivers like st7735 won't build on the Arduino UNO.
It is the RGBA function call.
func (c RGBA) RGBA() (r, g, b, a uint32) {
r = uint32(c.R)
r |= r << 8
g = uint32(c.G)
g |= g << 8
b = uint32(c.B)
b |= b << 8
a = uint32(c.A)
a |= a << 8
return
}This results in a SIGSEV during build
fatal error: unexpected signal during runtime execution

Is there anything we could do to work arround this issue?
Tests were done based on #1398 branch which is based on the current dev branch.
