Use system liblinear instead of using included liblinear.
liblinear in buildroot is at version 2.20 released on December 2017
whereas liblinear in nmap has not been updated since 7 years (except for
liblinear.vcxproj which has been updated 2 years ago)
Do not use --with-liblinear option as otherwise nmap will forget to add
-llinear to LIBS due to the following line in configure.ac:
if test $have_liblinear != yes; then
AC_CHECK_HEADERS([linear.h],
AC_CHECK_LIB(linear, predict, [have_liblinear=yes; LIBLINEAR_LIBS="-llinear"; break],, [-lm])
)
