Subject: kernel: guard include of signal.h more precisely.
X-Git-Tag: working-ls180~473^2
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7137f99658903e88ce78411097164c8caec661c8;p=yosys.git

kernel: guard include of signal.h more precisely.

Upgrading to WASI SDK 11.0 caused the WASM build to fail because WASM
does not have signals. (Arguably Yosys was broken even before, it was
just broken silently.)
