+From:	 Kevin Bortis <pkgs@bortis.ch>
+
+The attached patch fixes issues with musl libc on linux. musl does
+implement the POSIX 2008 standard termios.h on linux and does not
+include the non standard interface termio.h.
+
+The problem with dlinfo does no longer exists, since musl has
+implemented the required interface.
+
+This closes #2823 for me.
+
+Tested version:
+musl libc: 0.9.13
+openssl git: 1769dfab06dcf93a1c310ca7ea9531afcc448d0a
+
+Comparison of termios.h implementation on linux:
+
+glibc 2.17: does implement termios.h, passes make test
+musl 0.9.13: does implement termios.h, passes make test
+uClibc 0.9.33.2: does implement termios.h, not tested
+dietlibc 0.33: does implement termios.h, not tested
+
+I don't know the reason why termio.h is prefered on linux, since
+termios.h is generally prefered and implemented by all major libc
+implementations.
+
+Regards
+Kevin
