* guix/build/gnu-build-system.scm (gnu-build): Leave
%DEFAULT-PORT-CONVERSION-STRATEGY unchanged when 'string->bytevector'
fails to convert to ISO-8859-1. This is an attempt to work around the

Suggested by Mark H Weaver.

for 'extension/configure'.
Fixes <http://bugs.gnu.org/18895>.

parameter. Remove 'bindirs'. Add 'bin-directories',
'output-bindirs', and 'input-bindirs'. Use them instead of (getenv
"PATH") to as the argument to 'patch-shebang'.
This is a followup to 856ae5e. See <http://hydra.gnu.org/build/180506>

* guix/build/gnu-build-system.scm (strip): Check whether 'file-exists?'
before calling 'elf-file?' and 'ar-file?'. This should fix build
failures in the presence of dangling symlinks, as in
<http://hydra.gnu.org/build/167521/nixlog/1/raw>.
This avoids uncaught exceptions when the 'strip' phase would call these
procedures on symlinks to directories, such as 'lib/terminfo' in

Add 'id' field to 'user-group' form.
