34debf7a6d36bbd9a52e68e079ddfc446faf5bef Modify .travis.yml to explictly pass no in env vars instead of setting to nothing (Elichai Turkel)
ef37761feed0172baa03dd94c842f1547bdf3016 Change travis.sh to check if variables are equal to yes instead of not-empty. Before this, setting `VALGRIND=wat` was considered as true, and to make it evaluate as false you had to unset the variable `VALGRIND=` but not it checks if `VALGRIND=yes` and if it's not `yes` then it's evaluated to false (Elichai Turkel)

Instead of supporting configuration of the field and scalar size independently,
both are now controlled by the availability of a 64x64->128 bit multiplication
(currently only through __int128). This is autodetected from the C code through
__SIZEOF_INT128__, but can be overridden using configure's
--with-test-override-wide-multiply, or by defining
USE_FORCE_WIDEMUL_{INT64,INT128} manually.
not-empty.
Before this, setting `VALGRIND=wat` was considered as true, and to make it
evaluate as false you had to unset the variable `VALGRIND=` but not it
checks if `VALGRIND=yes` and if it's not `yes` then it's evaluated to
false
When $USE_HOST or $EXTRAFLAGS are empty, we pass (due to quoting) an
empty string as a parameter to ./configure, which then believes we want
to use a deprecated syntax for specifing a host or a target and yells at us:
> configure: WARNING: you should use --build, --host, --target
The fixes are:
- $EXTRAFLAGS could contain multiple flags and should not be quoted at all.
- We can get rid of $USE_HOST by specifying --host="$HOST" directly.
