Silence gcc-8 warnings
All of these warnings were false positives. -Wstringop-truncation is
particularly annoying when it warns about strncpy used quite correctly.
bfd/
* elf-linux-core.h (swap_linux_prpsinfo32_ugid32_out): Disable
gcc-8 string truncation warning.
(swap_linux_prpsinfo32_ugid16_out): Likewise.
(swap_linux_prpsinfo64_ugid32_out): Likewise.
(swap_linux_prpsinfo64_ugid16_out): Likewise.
* elf.c (elfcore_write_prpsinfo): Likewise.
gas/
* stabs.c (generate_asm_file): Use memcpy rather than strncpy.
Remove call to strlen inside loop.
* config/tc-cr16.c (getreg_image): Warning fix.
* config/tc-crx.c (getreg_image): Warning fix.
