AFAICT, libc_cv_cc_pie_default is only to set -fno-pie for non-PIE
linking with a toolchain that defaults to pie. PIE linking otherwise is
controlled accross the board with libc_cv_pie_default, which includes
build-pie-default, static-pie and now pie-programs.
So I reckon it is integrated; the new pie-programs variable is only to
set CFLAGS to -fPIC.
