Please take a look at hl/pie/static branch:

https://sourceware.org/git/?p=glibc.git;a=shortlog;h=refs/heads/hl/pie/static

I only tested it on x86-64.  You need binutils 2.29 branch or master branch
for

https://sourceware.org/bugzilla/show_bug.cgi?id=21782

I got these regressions:

FAIL: nptl/tst-cancel21-static
FAIL: nptl/tst-cancel24-static
FAIL: nptl/tst-cond8-static
FAIL: nptl/tst-mutex8-static
FAIL: nptl/tst-mutexpi8-static
FAIL: nptl/tst-sem11-static
FAIL: nptl/tst-sem12-static

I am looking into them.
