Subject: configure: Add check for bunzip2 and maintainer-mode tools.
X-Git-Tag: elfutils-0.162~28
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4664fd5871918cbf3afc6c9364e2b5117deecb1a;p=thirdparty%2Felfutils.git

configure: Add check for bunzip2 and maintainer-mode tools.

Without bunzip2 make check cannot be run. To generate all files in
maintainer-mode flex and bison are needed. Otherwise check that
libdw/known-dwarf.h is already generated.
