Hi all; autofs's configure.in is not properly set up to allow for
cross-compiling. It fails trying to detect -fPIE, because configure.in
runs AC_RUN_IFELSE to run a program (which of course can't work during
cross-compilation) and does not provide a cross-compilation result.
I'm not sure why this test for PIE exists or if it's really needed, but
if you want to keep it please add an argument for cross-compilation.
Patch is attached, against 4.1.4 (but I checked 5.00beta1 and it had the
same issue). As recommended by the autoconf manual, this patch is
pessimistic and assumes no PIE support for all cross-compilation
environments.
I've split the patch into two: one for configure.in and one for
configure itself (I'm not sure if you source code control the configure
script: some projects do and some don't).
Cheers!
