Turn off allow_double again, for callingconv test on arm-nacl-gcc.
Turn off allow_double again, for callingconv test on arm-nacl-gcc.

Before the change https://codereview.chromium.org/22866024/diff/23001/tests/callingconv/nacl.scons
the allow_double setting was always off for ARM (both clang and gcc).
After that change, allow_double was turned on for gcc, which is
now tickling a bug where constant pool entries (e.g., to hold the
double literals) can be too far away from the code. Turn off again.
