guile: Specify directories to find proper libunistring, libgmp and libltdl
Just when building on host which doesnt have libunistring on host guile
fails the following configure test
| configure: error: GNU libunistring is required, please install it.
| Configure failed. The contents of all config.log files follows to aid
debugging
The reason is that its looking for libunistring dev files on build
system, so lets point the configure into target sysroot, similar issue
exist for libgmp, libltdl detection as well, fixed thusly
Get rid of trailing whitespaces while here
