Arrange so that glibc uses 'TRIPLET-objdump -f' rather than 'objdump -f'
to determine the 'OUTPUT_FORMAT' value in libc.so when cross-compiling.

Patch submitted upstream:
  <https://sourceware.org/pipermail/libc-alpha/2021-July/128333.html>.

‘target-hurd?’.

Until now, we were unconditionally using ‘glibc-utf8-locales’, which
targets the glibc version used on Linux (2.35) rather than that used on
the Hurd (2.37).  This would lead to build failures due to the inability
to use locale encoding when targeting i586-gnu.

* gnu/packages/base.scm (glibc-utf8-locales/hurd): New variable.
* gnu/packages/commencement.scm (glibc-utf8-locales-final/hurd): New
variable.
(%boot5-inputs): Use it when ‘target-hurd?’ returns #t.
(%final-inputs): Likewise.
