Quick question that might sound silly, but I believe worth asking: why
are you taking this terribly complicated path to build SDL2_ttf
manually, rather than creating a Buildroot package directly?

The Buildroot autotools package infrastructure already handles most of
the cross-compilation problems by itself. So all this terrible dance of
CFLAGS and LDFLAGS, copying of sysroot and stuff that you're doing
would have been completely unneeded if you had done a Buildroot package
from the beginning.

It seems to me like you've wasted a huge amount of time :-/

Best regards,

Thomas
