We can fallback to the full set of default libs if we can not use the
"-nodefaultlibs" and "-l" options. But the key part of the patch is to set the
"-B" flag. It does not seem like we can use
gcc_jit_context_add_command_line_option instead of
gcc_jit_context_add_driver_option to pass "-B".

This means that we would need to use setenv() to define GCC_EXEC_PREFIX before
calling libgccjit, right?

Regarding the CRT part this is what I read to understand why I needed to add so
many libraries:
