[PATCH] libsframe: accept --target configure option

[PATCH] libsframe: accept --target configure option

[Clément Chigot]

Libsframe was missing AC_CANONICAL_TARGET, meaning that --target was
ignored. This could prevent libsframe.a to be installed in some cases,
the host fetching its canonical value while the target isn't. Both
having a different value, INSTALL_LIBBFD would be false.

OK, but please regenerate libsframe/Makefile.in too.
