configure: build position independent executables on x86-Linux hosts
PIE binaries cannot be linked with non-PIE binaries and make is not
smart enough to rebuild when the CFLAGS have changed.
Breaks build on RHEL-5 and probably also other not-so-recent linux distros.

It can be worked around by replacing "-fpie" with "-fpic" or (to avoid a
rather bad performance degradation) "-fpic -ftls-model=initial-exec" but
it's a bug in the linker and it should be fixed in RHEL:
