Number after .so is abi version, it is always 1 for libgcc_s.
Most linux systems set default library versions via symlinks that are
simply followed to get actual elf, however conda does it via linker
scripts which ctypes doesn't follow (below contents of libgcc_s.so):
```
/* GNU ld script
Use the shared library, but some functions are only in
the static library. */
GROUP ( libgcc_s.so.1 -lgcc )
```
ctypes.util.find_library thinks that this is the actual elf and
ctypes.CDLL just loads this text file as a shared library. The result
is:
```
File "/home/me/src/tinygrad/tinygrad/device.py", line 223, in CPUProgram
helper_handle = ctypes.CDLL(ctypes.util.find_library('System' if OSX else 'gcc_s'))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/home/me/miniforge3/envs/tinygrad/lib/python3.12/ctypes/__init__.py", line 379, in __init__
self._handle = _dlopen(self._name, mode)
^^^^^^^^^^^^^^^^^^^^^^^^^
OSError: /home/me/miniforge3/envs/tinygrad/lib/libgcc_s.so: invalid ELF header
```
