Fix bind 9.4.3_p2 cross-compilation

[Beber]

Hi,

bind-tools default configure is wrong when searching for epoll when
cross-compiling. So
bind-tools-BJA-epoll-AC_TRY_RUN-cross.diff correct that to not do a
non-conditional fail if cross-compiling :

checking epoll support... configure: error: cannot run test program while
cross compiling
See `config.log' for more details.

Then "gen" is compiled for many purposes in build. This binary is build
with
destination toolchain, do can't be executed on host.
bind-tools-BJA-gen-HOSTCC.diff correct that (host is x86_64-pc-linux-gnu,
while dest is i586-geode-linux-uclibc) :
