Document that --enable-static-pie implies PIE
To build static PIE, all .o files are compiled with -fPIE. Since
--enable-static-pie is designed to provide additional security hardening
benefits, it also implies that glibc programs and tests are created as
dynamic position independent executables (PIE) by default for better
security hardening.
