package/gnutls: disable for static build
The gnutils code uses __attribute__((constructor)) and
__attribute__((destructor)) to call constructor/desctructor when a
shared library is loaded.
Constructor/desctructor are not used when a static library is used
(except when if -Wl,--whole-archive -lgnutls -Wno-whole-archive is
used, not tested).
Even if gnutls initialization (_gnutls_global_init()) may be
called manually, the gnutls maintainer said it's not supported [1].
"Note that static linking applications with gnutls is not something
supported. gnutls relies on library constructors and destructors
which are not loaded when linking statically."
Now the gnutls script warns about static linking [2].
So disable gnutls statically by adding "depends on !BR2_STATIC_LIBS"
at Kconfig level and --disable-static in GNUTLS_CONF_OPTS.
Fixes:
