make fails: recompile with -fPIC

[Peter VARGA]

CXXLD libtest/backtrace

fails:
/bin/ld: libtest/backtrace_test.o: relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC

I run it with ./configure --prefix=/usr/glibc/libmemcached --disable-sasl:
Attached the config.log file.

Update:

I am using another glibc version than the system has. This error occurs when the LDFLAGS variable does not have a value. When I export LDFLAGS to the path of the new glibc version then I can compile it but the summary differs.

Summary when LDFLAGS is set:
Configuration summary for libmemcached version 1.0.18
