Hi up there,

a small update for the issue on armel (armvt4, armvt5t).

I added '-mthumb -mfloat-abi=soft -mfpu=neon' to CXXFLAGS and the build
was going till the end until the final big linking is done. And then ...
it fails again.

So I tried to understand what this 'relocation truncated' means [1]. But
this is area there I'm definitely not an expert. The longer I'm thinking
about I assume it's better the solution will be made upstream.

I tried to add 'Wl,--image-base -Wl,0x10000000' to LDFLAGS but cmake
isn't happy about this and I gave up for now.

For Debian we want to support much as possible of the hardware platforms
so I don't like to drop KiCad on armel if upstream isn't abandoned this
platform. Anyone has a idea how to proceed here?
