`LLVM_FLAGS="${FLAGS} -nostdinc++ -I${ZLIB_BUILD} -I${LIBCXX_BUILD}/include/c++/v1 -Wno-error=global-constructors"` should use a scheme similar to D108836 <https://reviews.llvm.org/D108836>.
@eugenis Can you make such a change to sanitizer bots?

Perhaps switch from `-I` to `-isystem` while touching the line.
