  [libc] Fix unit test compile flags propagation. (#106128)

With this change, I was able to build and test for aarch64 & riscv64 on
x86-64 host as follow:

Pre-requisite:
- cross build toolchain for aarch64
```
$ sudo apt install binutils-aarch64-linux-gnu gcc-aarch64-linux-gnu g++-aarch64-linux-gnu
```
- cross build toolchain for riscv64
```
$ sudo apt install binutils-riscv64-linux-gnu gcc-riscv64-linux-gnu g++-riscv64-linux-gnu
```
- qemu user:
```
$ sudo apt install qemu qemu-user qemu-user-static
```

CMake invocation:
```
$ cmake ../runtimes -GNinja -DLLVM_ENABLE_RUNTIMES=libc -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DLIBC_TARGET_TRIPLE=<aarch64-linux-gnu/riscv64-linux-gnu> -DCMAKE_BUILD_TYPE=Release -DLIBC_TEST_COMPILE_OPTIONS_DEFAULT="-static"
$ ninja libc
$ ninja check-libc
```
