[libc-commits] [libc] [libc] Enable bind test for riscv (PR #100132)

[Mikhail R. Gadelha via libc-commits]

https://github.com/mikhailramalho created https://github.com/llvm/llvm-project/pull/100132

The bind test was failing in the rv32 build bot because of how the build bot was setup to run the tests: we were using shared directories between the host and qemu and the bind functions was trying to create a file in this directory, thus creating it in the host machine.

The OS was returning "-1 ENXIO (No such device or address)", so we changed the rv32 buildbot to copy the binaries to qemu and dropped the shared directories feature.

A clean run (where all tests need to be copied to qemu) is taking 7 min, up from 3 min. Incremental runs still run in 3 min.
