Haven't tried with 5.10.1, but here's my 5.8.8/2.0.4/2.2.8 settings:

perl -V | grep -i fpic
    cc='cc', ccflags ='-fPIC -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm',
    cppflags='-fPIC -I/usr/include/gdbm'
    cccdlflags='-fpic', lddlflags='-shared'

Have you tried passing -fPIC at perl configure time when it asks for
additional CFLAGS?
