------------------------------------+----------------------------------
 Trying to build Tor 0.2.5.x with a cross-compiling toolchain and
 `./configure --host=arm-unknown-linux-gnueabihf`, the build process stops
 with the following error (followed by a number of warnings about bitshifts
 exceeding type width):

 `  CC     src/ext/curve25519_donna/src_common_libcurve25519_donna_a-
 curve25519-donna-c64.o`

 `src/ext/curve25519_donna/curve25519-donna-c64.c:35:1: error: unable to
 emulate 'TI'`

 `typedef unsigned uint128_t attribute((mode(TI)));`

 curve25519-donna-c64.c is the curve25519 implementation for 64 bit
 platforms and shouldn't be built for arm.
