+# Fix shared library building in XZ Utils 5.2.13, 5.4.7, and 5.6.2
+#
+# The releases were made with a development version of GNU Libtool
+# (2.5.0+1+g38c166c8). The benefit is that there tend to be fixes that
+# aren't in a stable release yet. At the same time there is a higher
+# risk of new bugs. Unfortunately there was a bug that breaks building
+# of shared libraries on some systems like mips64.
+#
+# This patch was made by taking the upstream commit to m4/libtool.m4
+# and then running "autoconf" to update the generated "configure".
+# This patch only modifies "configure" so that the changed timestamps
+# won't cause the build system to regenerate more files, which would
+# only work if one has all Autotools packages installed.
