[Buildroot] [git commit] c-icap: avoid host library search path

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=fcebe9f1f8d44fbd642330ee498268d49f2238d4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Add AUTORECONF as a workaround to the effect of '-Wl,-rpath -Wl,/usr/lib' that
c-icap adds to the linker command.
