This PR is the first step enabling support for native modules
for AIX. The main issue is that unlike linux where all
symbols within the Node executable are available to the shared
library for a native module (npm), on AIX the symbols must
be explicitly exported. In addition, when the shared library is
built it must be linked using a list of the available symbols.
This patch covers the changes need to:
1) Export the symbols when building the node executable
2) Generate the file listing the symbols that can be used when
building the shared library.
For AIX, it breaks the build process into 2 steps. The first builds
a static library and then generates a node.exp file which contains
the symbols from that library. The second builds the node executable
and uses the node.exp file to specify which symbols should be
exported. In addition, it save the node.exp file so that it can
later be used in the creation of the shared library when building
a native module.
The following additional steps will be required in dependent projects
to fully enable AIX for native modules and are being worked
separately:
- Updates to node-gyp to use node.exp when creating the
shared library for a native module
- Fixes to gyp related to copying files as covered in
https://codereview.chromium.org/1368133002/patch/1/10001
- Pulling in updated gyp versions to Node and node-gyp
- Pulling latest libuv
These changes were done to minimize the change to other platforms
by working within the existing structure to add the 2 step process
for AIX without changing the process for other platforms.

* Exclude `derb.cpp` as well as `derb.c` from Node builds

ICU 56 renamed derb.c to derb.cpp because of C++ yay.
This broke the exclusion of "derb.c" when building tools.
Solution is to add derb.c AND derb.cpp to exclusion.
We don't build the 'derb' tool, so it's fine to list the

This is an adaptation of 8e80528453.
Original commit message:
The MSI install scope was set to the WiX default, which is per-user.
However, with UAC, it could not be installed by a standard user
because InstallPrivileges is elevated by default, hence the install
scope should be set to per-machine. Furthermore, the default install
path is a per-machine location and setting the system path requires
administrator privileges.
By changing the InstallScope to perMachine, Start Menu shortcuts are
placed in ProgramData and not the installing user's AppData folder,
making the shortcuts available to other users. This also fixes the
installation when AppData is a network folder.
The custom action is necessary to allow upgrades. Since a per-machine
MSI cannot upgrade an application installed per-user, the custom
action checks if there is going to be an upgrade to a previous
version installed per-user and sets the installation as per-user to
allow upgrading. Hence, the advantages of installing per-machine will
only apply in fresh installations.
