we should not add explicit declaration there.
arm_neon.h contains those prototype already. they will be available if the
compiler configuration is with related builtin predefine, for example
__ARM_FEATURE_CRYPTO.
so, actually, if there is any warning when compile these test programs, they
are expected,
and we rely on these warnings to check whether certain features are available.
previously, I only verified on arm-none-linux-gnueabi cross check, so have not
exposed
these regressions.
no verified on arm-none-linux-gnueabihf, regression gone away on arm directory.
make check RUNTESTFLAGS="aapcs.exp neon.exp acle.exp simd.exp arm.exp"
ok for trunk?

* lib/target-supports.exp
(check_effective_target_arm_crypto_ok_nocache): Remove declaration for
