I adapted the patches to enable cross compiling to the
new file hierarchy and line numbers:
+ configure and libltdl/configure have just different line numbers
+ libltdl/config/ltmain.m4sh was replaced with build-aux/ltmain.{in,sh}
+ tests/cdemo does no longer exist
+ patched tests/testsuite and tests/sysroot.at instead
+ had to add --force to ./bootstrap
+ gmp now needs to run autoreconf -if for cross compile case
+ libarchive -"-
I successfully built for x86_64 and cross built for armv[67]hf e.g.
`alsa-lib` for a test. However, this pr needs to be scrutinized before merge.
