Package: gcc-6-arm-linux-gnueabihf
Version: 6.1.1-9cross1
Severity: important

Dear Maintainer,

If I cross-compile any code (even a basic hello-world) and then attempt
to link the resulting objects on the target system (stretch, armhf)
using the native gcc-6 toolchain (which is 6.2.0 in testing and has
already been for a while) I get the following failure:

/usr/bin/ld: hello.o: relocation R_ARM_THM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC
hello.o: error adding symbols: Bad value
collect2: error: ld returned 1 exit status

Recompiling with -fPIC as suggested does in fact fix the problem, but
this should not be necessary and never has been.  (Compiling without it
but linking with the cross-toolchain also results in a working binary.)

Note that cross-compiling + native linking is for example needed to be
able to use distcc to speed up compilation on small ARM systems by
delegating most of the work to a build server, which is how I ran into
this issue.  This setup is currently completely broken due to this bug.
