termiox was removed from linux in e0efb3168d34
Some more information available in https://www.spinics.net/lists/linux-serial/msg41926.html
Attempting to use the termiox ioctls on more modern kernels results in
"Inappropriate IOCTL" errors.
While the "right" solution might be to remove the termiox code from the
linux path, simply not checking for termiox builds a libserialport that
functions on modern linux kernels.

I don't think these two mentions of cygwin ever did anything useful.
In fact they stop libserialport being buildable under cygwin.
The first one caused builds on cygwin to try to build windows.c,
which uses the Win32 API, not the POSIX layer provided by cygwin.
The second asserts that enumeration and port metadata are supported
on cygwin, but that isn't the case.
Without these matches for cygwin as $host_os, libserialport builds
and works just fine on old-school cygwin with the original mingw32.
The only reason that MSYS2 worked better is that it uses "msys" as
the $host_os identifier, not cygwin.
Buildroot can create toolchains for the no-MMU flavour of Linux, with a triple
containing 'uclinux' instead of just 'linux'.

The last release (0.1.0) had the libtool version (current:revision:age)
set to 0:0:0. Since this release doesn't change/remove any
interfaces (it does *add* new interfaces, though), 'current' and 'age'
are increased and 'revision' is set to 0, resulting in 1:0:1.

Programs using libserialport don't need to be recompiled or relinked.

Also, add -Wshadow to the list of default compiler options.
$build and $build_os refer to the machine on which the software is
built, $host and $host_os refer to the machine for which the software
is (cross-)built.
The variables $target and $target_os (despite the confusing names)
are only relevant in the context of building cross-compilers.
Since we now require MinGW-w64, we no longer have to set WINVER manually,
since MinGW-w64 defaults to WINVER=0x0502 (which corresponds to
Windows Server 2003 SP1 / Windows XP SP2 apparently, which is fine for us).
Any libs needed when building static binaries must be listed in the
'Requires.private' field of the installed pkg-config file libserialport.pc.
Currently, this is libudev (but only when building on/for Linux).
