Changes v1 -> v2 (after review of Thomas Petazzoni):
 - Do not call autogen.sh, use AUTORECONF and apply the same tweaks
   than autogen.sh to remove de-ANSI-fication

This was still causing the AC_CHECK_LIB error here, which was in fact
due to the use of PKG_CHECK_MODULES without having host-pkgconf in the
dependencies. With this, ngircd built fine, but unfortunately, there is
still an issue.

This ${SERIAL_TESTS}

and here, cause check-package to complain:

package/ngircd/ngircd.mk:23: use $() to delimit variables, not ${}
package/ngircd/ngircd.mk:26: use $() to delimit variables, not ${}

so we need to find a way to either silence those warnings, or work
around them. Perhaps we could simply include a patch ?

The tarball already has the configure.ac and Makefile.am generated,
they only need to be tweaked for de-ansi-fication, and a patch may be a
good alternative.

What do you think ?

Best regards,

Thomas

 Pretty please, be consistent with sed delimiters:

$ git grep -h '\(SED\|sed\|-e\).*\bs[@!|,#+%^:]' -- \*.mk | \
  grep -o '\bs[@!|,#+%^:]' | sort | uniq -c
     23 s#
     56 s%
     60 s,
     50 s:
      2 s@
      3 s^
     11 s|

 So comma or percent please.

 Huh? How could this ever have worked? make will replace the ${SERIAL_TESTS}
with the empty string, since the SERIAL_TESTS variable is not defined. Fabrice,
did you actually test this? Or maybe the SERIAL_TESTS is empty anyway?

 Anyway: $$ will fix the issue, both for make and for check-package.

 Regards,
 Arnout

SERIAL_TESTS would be "serial-tests" in our case:

  https://github.com/ngircd/ngircd/blob/master/autogen.sh#L190

https://www.gnu.org/software/automake/manual/html_node/Serial-Test-Harness.html

I guess it's only used when you run "make check", so we don't really
care in the context of Buildroot.
