Depend on proper XML escaping from the Ellidiss GUI and then from ASN1SCC.

Which does not work with gnat2017

Learn the compiler and linker flags, by calling out into
a temporary Makefile that includes the Ocarina-generated one
(see instructions from Jerome in ticket 311)

But don't do this for RTEMS! Because for this to work, we
need to wait for access to the EnvVars information...
The Ocarina-generated makefile depends on proper setting
of RTEMS_MAKEFILE_PATH, which itself depends on the
deployment processor.

Patch to compensate a bug in the CV Update from TASTEv2.1.4 makes it copy non-AADL files in that folder during the build

For a specific grammar used by GMV, ASN1SCC emits LLONG_MIN - which as
per limits.h ...

    #  ifdef __USE_ISOC99

    /* Minimum and maximum values a `signed long long int' can hold.  */
    #   define LLONG_MAX 9223372036854775807LL
    #   define LLONG_MIN (-LLONG_MAX - 1LL)

In plain words, we need -std=c99 during the build.
