+Subject: Fix compilation with different ucontext_t on musl

+Author: Simon Frankenberger <simon-alpine@fraho.eu>
+
+The machine state registers have to be accessed differently when
+running on musl libc. This patch fix this by replacing
+"uc_mcontext.regs->grp" with "uc_mcontext.gp_regs"
+and accessing the named fields (like "->nip") by the array index constants.
