[COMMITTED 05/32] ada: Add System definitions of SIGSYS for Android

[Marc Poulhiès]

From: Olivier Hainque <hain...@adacore.com>

This allows reusing a-intnam__linux.ads for Android.

gcc/ada/ChangeLog:

        * libgnarl/s-linux__android-arm.ads: Define SIGSYS.
        * libgnarl/s-linux__android-aarch64.ads: Define SIGSYS.
        * libgnarl/s-osinte__android.ads: Expose SIGSYS value.

Tested on x86_64-pc-linux-gnu, committed on master.
