OK, this is my bad:
* The fix to Makefile.am is to replace the first CFLAGS assignment from "=" to
"+="
* Also note that CFLAGS should be passed to ./configure and not make (as
"./configure --help" nicely mention).
Here is a patch:
diff --git a/Makefile.am b/Makefile.am
index d43ce91..9dd64b2 100644
--- a/Makefile.am
+++ b/Makefile.am
@@ -5,7 +5,7 @@ LEGACY_MAKE = \

Normally, "-fPIC" isn't needed when linking an executable (only on shared
objects).
Can you share more info about the build environment?
* Linux distribution and version (some redhat?)
* Primary tools versions (e.g: the output of "rpm -q rpm -q gcc make libtool
automake autoconf rpm")
* Extra stuff? maybe building an RPM? (which adds some extra
distribution-specific CFLAGS, etc.)
The reason, is that I didn't encounter this failure either with/without "-fPIC"
and I'd like to try and re-create it.
Thanks for the report,
