From:	 Kevin Bortis 

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
