+Subject: [PATCH] qmake: fix libtool la file dependency_libs entries
+
+Some versions of libtool does not handle absolute pathes for dynamic
+libraries, e.g.:
+
+  libtool:   error: cannot find the library '' or unhandled argument '/data/buildroot/buildroot-test/instance-0/output/host/riscv64-buildroot-linux-gnu/sysroot/usr/lib/libQt5Widgets.so'
+
+So change la file dependency_libs entries to -L<path> -l<library> version.
