Quartus does the same thing. It has its own lib directory with its own
binary versions of standard libraries, which is a bit annoying because when
it tries to spawn processes (like a web browser to read the documentation)
they inherit the LD_LIBRARY_PATH and will sometimes explode because
libstdc++ is compiled with the wrong version of gcc
