[Buildroot] [PATCH 1/3] package/libdill: autoreconf needs host-pkgconf

[Buildroot] [PATCH 1/3] package/libdill: autoreconf needs host-pkgconf

[Bernd Kuhls]

Fixes error during autoreconf when openssl is not selected:

configure.ac:119: error: possibly undefined macro: AC_CHECK_LIB
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure.ac:127: error: possibly undefined macro: AC_MSG_ERROR

As it turns out adding host-pkgconf as mandatory dependency fixes the
problem.

Fixes:

Ah indeed, host-pkgconf! Thanks for coming up so quickly with an
improved patch.

However, since when this problem is happening? Again, need to
understand if this needs to be backported to LTS or not.

Thanks!
