[PATCH] Use crtbeginT.o and crtend.o for non-PIE static executables

[PATCH] Use crtbeginT.o and crtend.o for non-PIE static executables

[H.J. Lu]

When static PIE is enabled by default, we shouldn't use crtbeginS.o and
crtendS.o for non-PIE static executables.  Check $($(@F)-no-pie) to use
crtbeginT.o and crtend.o to create non-PIE static executables.
