config.mak.uname: add sysinfo() configuration for cygwin

Although sysinfo() is a 'Linux only' function, cygwin provides an
implementation which appears to be functional. The assumption that
this function is Linux only is reflected in the way the HAVE_SYSINFO
build variable is handled by the Makefile and config.mak.uname.

Rework the setting of HAVE_SYSINFO in the Linux section of the system
specific config file, along with the corresponding setting of the
BASIC_CFLAGS in the Makefile. Add the setting of HAVE_SYSINFO to the
cygwin section of 'config.mak.uname'. While here, add a test for the
sysinfo() function to the autoconf build system.
