Many of the FP tests fail in AArch64 soft nofp because, due to the lack of FP instructions, clang emits calls to `fma`, but its definition is missing from the hermetic C library put together for the hermetic tests. Even if `libc.src.math.fma` is added to the `DEPENDS` lists for the tests, it doesn't work because the `fma` function is under a mangled internal namespace (`LIBC_NAMESPACE_DECL`), not in the global one, hence the linker still can't find the symbol.
One example of such test is `acosf_test`.
