Subject: [PATCH] build: Remove execinfo.h check

The check for the execinfo.h header is only advisory; the build will not
fail if it is not present, and set HAVE_EXECINFO_H if it is. The check
was added in commit bc3e020475e ("build: Add declaration checks to check for
required syscall flags") with no obvious use or reasoning.

Remove the no-op check.
