Previously the cmake file only sets `-std=gnu99` when it is on x86(-64),
which causes compilation failure on other architectures when gcc is
used.
GCC currently defaults to `-std=gnu23`, which would fail the build with:
blosc/shuffle.c:26:15: error: ‘bool’ cannot be defined via ‘typedef’
This patch fixes it by setting `-std=gnu99` for gcc on all
architectures.

Why first check if the compiler is gcc? If our code is written in the gnu99 dialect, it should be passed to any compiler. Clang also supports compiling gnu99 code. |

The original code sets it to
That's nice! But I suppose msvc don't support it? |
Contributor
I doubt. But how can it then compile the code? |
