They are so not-irrelevant that the GPL contains an explicit clause to handle this case, without which it would be very hard to write GPL applications on non-free platforms.
Maybe the section you quoted below is what makes the free-compiler question irrelevant then?
Btw, for some reason this discussion suddenly is about GPL, whereas FluidSynth is released under LGPL. Could we stay on topic by restricting us to discussing LGPL instead of GPL?
(This section also exists in LGPL, so the question is still relevant.)
In GPLv2 it's this: "However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable."

An application which relied on some proprietary compiler that was not covered by this clause would not be distributable under the GPL (which is fairly obvious, because otherwise it would be very easy to work around the GPL by putting all your proprietary changes into the compiler).
There is a problem with the section in itself, as it indicates that a compiler is a major component of an operating system. For the Windows platform in particular, a lot of different compilers exist.
For iOS, I think we can count XCode as being such a major component. The problem for me is with the input to the code signing tool, with requires an Apple subscription fee.
