Merge #297
297: Add a section to place the veneers in memory r=jonas-schievink a=hug-dev
The veneers are for now only generated by the Arm GNU linker when it
spots an entry function (one that was decorated with the
cmse_nonsecure_entry attribute).
Adding this section will allow to configure the SAU to make this section
Non-Secure Callable.
Doing tests locally I could not see any warnings if this section was empty so I think this is fine. It is highly specific to the GNU toolchain so maybe you would want some preprocessing directive and `cfg` options which I am happy to add.
There is documentation for the section name at the end of [this page](https://sourceware.org/binutils/docs/ld/ARM.html).
It needs to be aligned on 32 bytes as a requirement from the Security Attribute Unit.
