Like I posted earlier it works if I add --sysroot= to CFLAGS.
But I can't seem to get libtool to pass --sysroot= variable to the final link command in tslib package:


...

Manually adding --sysroot to gcc link command solves the problem, but it is not 'the way to go'. I've tried
adding -Wl--sysroot=.. but with no avail.

What switches must be used for libtool to pass sysroot parameter to the linker?

Thank you,
Hinko
