ACPICA: Clib: Add -nostdinc support for EFI layer
ACPICA commit d261d40ea168f8e4c4e3986de720b8651c4aba1c
This patch adds sprintf()/snprintf()/vsnprintf()/printf()/vfprintf()
support for OSPMs that have ACPI_USE_SYSTEM_CLIBRARY defined but do not
have ACPI_USE_STANDARD_HEADERS defined.
-iwithprefix include is required to include <stdarg.h> which contains
compiler specific implementation of vargs when -nostdinc is specified.
-fno-builtin is required for GCC to avoid optimization performed printf().
This optimization cannot be automatically disabled by specifying -nostdlib.
Please refer to the first link below for the details. However, the build
option changes do not affect Linux kernel builds and are not included.
Lv Zheng.
