Konstantin Belousov 62af2dc3fb rtld: ignore static TLS segments when tracing.
For PIE binaries, ldd(1) performs dlopen(RTLD_TRACE) on the binary.
It is legal for binary to use initial exec TLS mode, but when such
binary (actually dso) is dlopened, we might not have enough free space
in the finalized static TLS segment.  Make ldd operational by skipping
TLS space allocation, we are not going to execute any code from the
dso anyway.
