Detect as many warnings as possible during configure and enable them
if the user did not supply any, so that any such problem can be spotted
and fixed.

Some target platforms do not have <unistd.h>, notably Windows when
using vanilla MSVC toolchain. Note: The AC_CHECK_HEADERS([unistd.h])
is redundant with LT_INIT, but there is no guarantee for that.

[guillem@hadrons.org:
 - Use AC_CHECK_HEADERS instead of AC_CHECK_HEADER.
 - Quote argument to AC_CHECK_HEADERS. ]

There are platforms without <sys/param.h>, so we better avoid the
header altogether, and add the required MIN macro outselves.

This is not a widely supported feature, so only use if in case the
linker does support it.

We should use the autoconf macro instead of expecting the system to
provide the endianness information, which many do not.

[guillem@hadrons.org:
 - Use autoconf macro instead of gnulib one.
 - Slightly reword commit message. ]

We do not provide alternatives for when memset() is missing, or when
malloc() is not GNU-style malloc(), causing redirection to (undefined)
rpl_malloc(). We do not rely on GNU-style malloc() at all, so there is
no point in checking for it.
