# Make header for GPE PK builds
#
# The application may define the following variables to control the
# build process:
#
# IMG_INCLUDES : Aplication-specific header search paths
#
# DEFS : A string of -D<symbol>[=<value>] to control compilation
#
# PK : Default ..; The path to the PK source code.
# The default is set for building the PK
# subdirectories.
#
# PK_THREAD_SUPPORT : (0/1, default 1); Compile PK thread and
# semaphore suppprt
#
# PK_TIMER_SUPPORT : (0/1, default 1); Compile PK timer suppprt
#
# SIMICS_ENVIRONMENT : (0/1, current default 0); Compile for Simics
#
# SIMICS_MAGIC_PANIC : (0/1, current default 0); Use Simics Magic
# breakpoint for PK_PANIC() instead of PowerPC trap.
# Note that Simics does not model trap correctly in
# external debug mode.
#
# GCC-O-LEVEL : The optimization level passed to GCC (default -Os). May
# also be defined empty (GCC-O-LEVEL=) to disable
# optimization. This variable can also be used to pass
# any other non-default setting to GCC, e.g.
# make GCC-O-LEVEL="-Os -fno-branch-count-reg"
#
# GCC-TOOL-PREFIX : The full path (including executable file prefixes) to
# the GCC cross-development tools to use. The default is
# "ppcnf-mcp5-"
#
# CTEPATH : This variable defaults to the afs/awd CTE tool
# installation - The PORE binutils are stored there. If
# you are not in Austin be sure to define CTEPATH in
# your .profile.
#
# OBJDIR : target directory for all generated files
