After some very confused debugging, I discovered that GNU make has a
main() function with this signature:
int main(int argc, char** argv, char** envp)
Apparently this is a non-standard but widely supported thing, so let's
do the same in Serenity so make works as expected.
This fixes an issue where you had to do "make PATH=..." instead of make
just picking up PATH from the environment. :^)
