Subject: Add a stub pthread header.
X-Git-Tag: 24jan2021_ls180~2184
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b2710e437c57d61c80ff6780199cc3b61570cf44;p=litex.git

Add a stub pthread header.

The header implements only the pthread rwlock interface, which
never actually locks.

This is necessary to build libunwind.
