Define and handle TLS relocations for FDPIC in BFD and gas. In gas, the new relocations are rejected if the --fdpic option was not specified. We also define the __tdata_start symbol to mark the start of the .tdata section. This allows FDPIC static binaries to find the start of .tdata section, since phdr->p_vaddr of TLS segment is not a valid value for FDPIC. 2018-04-25 Christophe Lyon <christophe.lyon@st.com> Mickaël Guêné <mickael.guene@st.com> bfd/: * bfd-in2.h (BFD_RELOC_ARM_TLS_GD32_FDPIC) (BFD_RELOC_ARM_TLS_LDM32_FDPIC, BFD_RELOC_ARM_TLS_IE32_FDPIC): New relocations. * elf32-arm.c (elf32_arm_howto_table_2): Add R_ARM_TLS_GD32_FDPIC, R_ARM_TLS_LDM32_FDPIC, R_ARM_TLS_IE32_FDPIC relocations.

genscripts.sh sets some shell variables, then sources
EMULATION.sc, to generate EMULATION.{x,xr,xu,xn,xbn} -- the script
files for default, -r, -Ur, -n, -N.
