... please note that I am building out of tree. There are no
limpam_misc* inside the "buildroot tree" which includes the main source
tree. When the compilation fails, inside my "output tree":

  $ find -name "libpam_misc.so*"
  ./build/linux-pam-1.3.0/libpam_misc/.libs/libpam_misc.so
  ./build/linux-pam-1.3.0/libpam_misc/.libs/libpam_misc.so.0
  ./build/linux-pam-1.3.0/libpam_misc/.libs/libpam_misc.so.0.82.1
  ./target/usr/lib/libpam_misc.so
  ./target/usr/lib/libpam_misc.so.0
  ./target/usr/lib/libpam_misc.so.0.82.1
  ./host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/libpam_misc.so
  ./host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/libpam_misc.so.0
  ./host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/libpam_misc.so.0.82.1

Clearly, then, it is not finding the "./target/usr/lib/libpam_misc.so"
in "out-of-tree" build.

...I do...
