These tests fail on aarch64 and s390x for us:

=====FAIL: elf/tst-pie-address.out=====
=====FAIL: elf/tst-pie-address.test-result=====
FAIL: elf/tst-pie-address
original exit status 139
=====FAIL: elf/tst-pie-address-static.out=====
=====FAIL: elf/tst-pie-address-static.test-result=====
FAIL: elf/tst-pie-address-static
original exit status 132

The configure checks report this 

checking whether -fPIE is default... no
checking PDE load address... 0x0000000001000000
checking for linker that supports -Ttext-segment=0x0000000001000000... yes
checking if we can build programs as PIE... yes
checking if we can build static PIE programs... yes
