-Subject: [PATCH] fix build with musl
-
-signal.h already includes bits/sigcontext.h
-Documentation seems to indicate that if you need the definitions in
-sigcontext.h, you are supposed to include signal.h and not sigcontext.h.
-
-a good fix should be to remove glibc
-specific understanding, in those ifdef's
