Even if we do an override to papi get the proper configure flags for
cross-compiling, the memory fences are not defined for risc-v:
mb.h:67:2: error: #error Need to define rmb for this architecture!
Currently, we can use bscpkgs similarly to nixpkgs either through
the flake outputs or with import bscpkgs:
```nix
# currently supported:
bscpkgs.legacyPackages.x86_64-linux.hello
let pkgs = import bscpkgs { system = "x86_64-linux"; }; in pkgs.hello
```
The missing piece is nixpkgs.lib (not pkgs.lib, the system agnostic
one). The workaround is to do bscpkgs.inputs.nixpkgs.lib instead. We can
simplify this by forwarding the lib to our outputs.
This enables us to use bscpkgs as a drop-in
replacing the inputs to our flake from nixpkgs to bscpkgs.
(inputs.nixpkgs.url = "<*BSC*pkgs url>").

The rdma-core driver.h include is no longer installed:
56dd87acd2
So ibv_read_sysfs_file() is not defined. As the symbols is still
distributed, we simply add the missing prototype manually.
Similarly, the gaspi_get_system_mem() function is not available from the
gaspi public headers, so we define it in the max_mem.c test.
Fixes: #7

To support the new instrumentation for HWC it would be useful to already
build nOS-V with PAPI support enabled. The enablePapi switch allows it
to be disabled with `nosv.override { enablePapi = false; }`.

Adds a new patch to fix libxml2: the m4 AM_PATH_XML2 macro has been
deprecated and is no longer included in the latest nixpkgs unstable.
Upstream recommends using `PKG_CHECK_MODULES` instead.
