Fix recent STM324LXX patch to compile on 32-bit hosts.

	* elf32-arm.c (create_instruction_branch_absolute): Replace
	pointer parameters with a simple integer parameter.
	(stm32l4xx_create_replacing_stub_ldmia): Update calls to
	create_instruction_branch_absolute.
	(stm32l4xx_create_replacing_stub_ldmdb): Likewise.
	(stm32l4xx_create_replacing_stub_vldm): Likewise.
	(elf32_arm_write_section): Use pointer type for veneer addresses.
