[Patch,ARM] crypto intrinsics in AArch32 testsuite fix

[Christophe Lyon]

Hi,

Commit 206131 introduced check_effective_target_arm_crypto_ok in
lib/target-supports.exp, to check that the target supports
-mfpu=crypto-neon-fp-armv8 -mfloat-abi=softfp.

However, when GCC is configured for target arm-none-linux-gnueabihf, I
can see all the new tests fail:
sysroot-arm-none-linux-gnueabihf/usr/include/gnu/stubs.h:7:29: fatal
error: gnu/stubs-soft.h: No such file or directory

(stubs.h is included via arm_neon.h)

This is because check_effective_target_arm_crypto_ok sample test is
too simple. Making it include arm_neon.h does the trick (and makes the
tests UNSUPPORTED rather than FAIL).

OK?

Christophe.

    * lib/target-supports.exp (check_effective_target_arm_crypto_ok):
    Include arm_neon.h in sample test.
