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

It was created by MPIR configure 3.0.0, which was
generated by GNU Autoconf 2.72.  Invocation command line was

  $ ./configure --target=armeb-buildroot-linux-uclibcgnueabi --host=armeb-buildroot-linux-uclibcgnueabi --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 --enable-static --enable-shared
