Windows support: tikv-jemalloc-sys not compiling because sh is not a valid command.

[dertuxmalwieder]

While analyzing the issue mentioned in ezrosent/frawk#87, I found that tikv-jemalloc-sys (build.rs) relays on sh during its build process. As jemalloc, more or less, supports native compilation on Windows without any MinGW, bash, or other emulations of Unix-like platforms, I would suggest that the hard-coded sh call gets a forking path for Windows.

jemalloc relies on configure to bootstrap the build system, I'm not sure how to do so without sh. I believe jemalloc/jemalloc#303 is required to achieve cross platform support.

Probably, yes. I admit that I have never tried to use jemalloc itself on Windows, so my initial idea might be wrong indeed.

@BusyJay Hello, I have installed make on windows via Chocolatey, but still sh is a linux command. Would it be possible to remove sh during a build? Thanks.

And I don't know what this line is for https://github.com/tikv/jemallocator/blob/main/jemalloc-sys/build.rs#L161, seems like this is blocking for windows as well.

You can check https://github.com/jemalloc/jemalloc/blob/dev/INSTALL.md#building-for-windows for prerequisites of Windows platform.
