They are preventing autotools from checking netinet/sctp.h existence
successfuly which in turn makes configure.ac files with lines similar to
this to fail, even if DEPENDS="lksctp-tools" and netinet/sctp.h is
clearly available under recipe-sysroot/:
AC_CHECK_HEADERS(netinet/sctp.h,,AC_MSG_ERROR(netinet/sctp.h not found))
This is the case for new libosmo-netif versionsi (meta-telephony branch
laforge/nightly), which expects netinet/sctp.h to be available if default
flag --enable-libsctp is used.
Without this patch, do_configure will fail unless following line is used
in the recipe:
CACHED_CONFIGUREVARS += "${@bb.utils.contains('PACKAGECONFIG', 'libsctp', 'ac_cv_header_netinet_sctp_h=yes', '',d)}"
So removing ac_cv_header_netinet_sctp_h would be enough, but I couldn't
find any good information on why the other 2 variables were set in site
config files, hence no good reason to keep them.
