MKPIE breaks build

["Mecislav Salar" <mecislavsalar%googlemail.com@localhost>]

good day

i have read mk.conf(8) man page.

i would like to use this feature PIE (Position Independent
Executables). but building the important libc seems to break on a ld
error

collect2: ld returned 1 exit status

if I don not use PIE [MKPIE = no] i can build no problemo, great!
