Subject: [PATCH] configure.ac.in: Allow dynamic linking against ndpi 3.0

Linking statically is problematic since NDPI_LIBS is '-lndpi -lm'
and when we use -Bstatic it also brings in -lm to use libm.a and on some
architectures ( x86 ) which this does not work and results in missing symbols

Fixes
ipe-sysroot/usr/lib/libm.a(e_logf.o): in function `logf_ifunc_selector':
/usr/src/debug/glibc/2.35-r0/git/math/../sysdeps/i386/i686/multiarch/ifunc-sse2.h:30: undefined reference to `_dl_x86_cpu_features'

Upstream-Status: Submitted [https://github.com/ntop/ntopng/pull/6318]
