R_PPC64_TLSGD and R_PPC64_TLSLD are used as markers on TLS code sequences. For GD-to-IE and GD-to-LE relaxations, the next relocation R_PPC64_REL24 should be skipped to avoid "undefined symbol" (__tls_get_addr) error when linking statically.

R_PPC64_GOT_TLSGD16_HA
R_PPC64_GOT_TLSGD16_LO
R_PPC64_TLSGD R_TLSDESC_CALL
R_PPC64_REL24 __tls_get_addr
