xcompile: Explicitly disable warning address-of-packed-member
With GCC 9.x has a new warning *address-of-packed-member*. > -Waddress-of-packed-member > > Warn when the address of packed member of struct or union is > taken, which usually results in an unaligned pointer value. > This is enabled by default. This results in the build errors below, for example, with GCC 9.2 from Debian Sid/unstable. src/southbridge/intel/common/spi.c: In function 'spi_init': src/southbridge/intel/common/spi.c:298:19: error: taking address of packed member of 'struct ich7_spi_regs' may result in an unaligned pointer value [-Werror=address-of-packed-member] 298 | cntlr->optype = &ich7_spi->optype; | ^~~~~~~~~~~~~~~~~ Therefore, explicitly disable the warning.
