In canadian builds, the target toolchain running on the build
machine is not compiling and installing target Newlib. Thus it
cannot by itself link target executables. This results in
errors for gnuprumcu package when its configure script attempts
to test the compiler:
.../ld: cannot find crt0.o: No such file or directory
configure:3738: error: C compiler cannot create executables
Fix by passing the host toolchains's sysroot in target CFLAGS.
While at it, also add a missing passing of target LDFLAGS.
Successfully tested the following canadian builds:
x86_64-unknown-linux-gnu,pru
x86_64-w64-mingw32,pru
arm-unknown-linux-gnueabihf,pru

Changes since v0.5.0:
* Add spec files for am64x SoCs.
* Require Binutils at least version 2.37.
* Require pru-gcc to be installed.
* Remove linker scripts. Instead set memory sizes from specs.
* Activate --gc-sections linker option by default.
* The "--host=pru" configure option must be used instead of "--target=pru.

Include the gnuprumcu package in PRU cross toolchain.
Toolchain is somewhat useless without device specs and
linker scripts for the various SoCs.
