This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.71.  Invocation command line was

  $ ./configure --target=mips64el-buildroot-linux-uclibc --host=mips64el-buildroot-linux-uclibc --build=x86_64-pc-linux-gnu --prefix=/usr --exec-prefix=/usr --sysconfdir=/etc --localstatedir=/var --program-prefix= --disable-gtk-doc --disable-gtk-doc-html --disable-doc --disable-docs --disable-documentation --with-xmlto=no --with-fop=no --disable-dependency-tracking --enable-ipv6 --disable-nls --disable-static --enable-shared --disable-client --enable-libssh --with-protocols=bfd,ospf
