ISSOtm f234796428 Avoid allocating for our linkdef names (#2111)
This reverts a change introduced in fd78a9ae8, though it wasn't that commit's main point
so I'm feeling okay with undoing that.

This feels like an overkill change, using a static string is good enough for this
since we never modify this. I have considered using `string_view` instead, to have
the best of both worlds, but that's not NUL-terminated so our print functions
get a little grumpy.

Installing

The platform-specific installation instructions are available online. To build from source using make or cmake, briefly:

make
sudo make install
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build
cmake --install build

Both build systems support a prefix (e.g. to install into a specific directory) and a suffix (e.g. to append the version number or commit ID):

make
sudo make install PREFIX=install_dir/ SUFFIX=-$(git rev-parse --short HEAD)
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DSUFFIX=-$(git rev-parse --short HEAD)
cmake --build build
cmake --install build --prefix install_dir

On Windows, any SUFFIX should include the .exe extension.
