gnu: ld-wrapper-boot0: Work around strict evaluation of (%current-system).
Reported by Mark H Weaver <mhw@netris.org> Partly fixes <http://bugs.gnu.org/24832>. 'ld-wrapper-boot0' was evaluating strictly instead of lazily, leading to invalid system types. * gnu/packages/base.scm (make-ld-wrapper): Turn #:target into a one-argument procedure. Honor it. * gnu/packages/commencement.scm (ld-wrapper-boot0): Fix 'name' argument to 'make-ld-wrapper'. Make #:target argument a procedure. * gnu/packages/cross-base.scm (cross-gcc): Adjust #:target argument.master
