That looks like a toolchain build/configuration issue, not a test
issue. IIRC this comes up from time to time, something's probably
broken in riscv-gnu-toolchain but I'm not sure what's wrong.
I get a working setup with just `./configure --enable-linux
--disable-multilib` and the latest riscv-gnu-toolchain master. How
are you building things?
I've kicked off a few builds to confirm but I use:
The non-multilib runs finished and still have issues.
The missing-stubs failures go away when building with multilib - so at
least now I have something to compare against :)
I'll dig into why and see what's needed for non-multilib tests to pass.

git clone https://github.com/riscv-collab/riscv-gnu-toolchain
cd riscv-gnu-toolchain
git submodule update --init gcc
cd gcc && git checkout master && cd ..
mkdir build && cd build
../configure --prefix=$(pwd) --with-arch=rv32gcv --with-abi=ilp32d
Make sure you bump gcc to tip of tree!
The latest riscv-gnu-toolchain master uses gcc 12.2 which doesn't have
the testcases that are failing (rvv folder):
https://github.com/gcc-mirror/gcc/tree/2ee5e4300186a92ad73f1a1a64cb918dc76c8d67/gcc/testsuite/gcc.target/riscv
The failures only show up for tests in:
gcc.target/riscv/rvv/
gcc.dg/vect/costmodel/riscv/rvv/
After bumping gcc and using your command (with --prefix)
../configure --enable-linux --disable-multilib --prefix=$(pwd)
I still get the missing stubs failures.
I've also tried this with the build directory both inside and outside
the repo and that doesn't make a difference.

This also extends beyond math.h. I'm seeing similar failures for
testcases like
gcc.target/riscv/rvv/autovec/cond/cond_convert_int2float-rv64-1.c that
#include <stdint.h>.
