Title:
  ntp fails to cross-build

Status in dpkg-cross package in Ubuntu:
  Expired

Bug description:
  ntp fails to cross-build:

  Uses correct compiler but chooses wrong-arch header path

  arm-linux-gnueabi-gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I.. -I../include -I../lib/isc/include -I../lib/isc/nothreads/include -I../lib/isc/unix/include  -D_GNU_SOURCE -I/usr/include  -g -fno-strict-aliasing -O2 -Wall -Wcast-qual -Wmissing-prototypes -Wpointer-arith -Wshadow -Winit-self -Wstrict-overflow -Wno-strict-prototypes -c authkeys.c
  authkeys.c: In function 'authencrypt':
  authkeys.c:496:20: error: invalid 'asm': invalid operand for code 'w'
  authkeys.c:496:20: error: invalid 'asm': invalid operand for code 'w'

  The wierd thing is that this only happens if 
   -eCONFIG_SITE=/etc/dpkg-cross/cross-config.armel is specified.

  Running the debuild command without that causes it to get the include
  pathright, but not know how big it's LONGs are. Something in the
  autoconf cache variables is screwing it up, which suggests breakage in
  the configure file, because providing that info should not break the
  build.

  Background:
  The build command is:
  xdeb --only-explicit -a armel --prefer-apt --apt-source --debug --force-rebuild bash

  The actual build command xdeb issues is:
  debuild --no-lintian -eUSER -eCONFIG_SITE=/etc/dpkg-cross/cross-config.armel -eDEB_BUILD_OPTIONS=nocheck -eGTEST_INCLUDEDIR=/usr/arm-linux-gnueabi/include -eGTEST_LIBDIR=/usr/arm-linux-gnueabi/lib -ePKG_CONFIG_LIBDIR=/usr/arm-linux-gnueabi/lib/pkgconfig:/usr/arm-linux-gnueabi/share/pkgconfig:/usr/share/pkgconfig -eDH_VERBOSE=1 -aarmel -b -uc -us -tc
