https://llvm.org/docs/GettingStarted.html#host-c-toolchain-both-compiler-and-standard-library says that GCC 7.4 needs to be supported, so "gcc7.5 is probably getting a bit long in the tooth here" is not a problem.

However, a gcc 7.4 build on x86-64 works for me. I wonder whether this is a 32-bit specific problem or AArch32 GCC specific problem.
