[deliverable/binutils-gdb.git] / ld / configure.host

# This is the linker host specific file.  This is invoked by the
# autoconf generated configure script.  Putting it in a separate shell
# file lets us skip running autoconf when modifying host specific
# information.

# This file sets the following shell variables:
#  HDEFINES		host specific compiler flags
#  HOSTING_CRT0		crt0.o file used for bootstrapping
#  HOSTING_LIBS		libraries used for bootstrapping
#  NATIVE_LIB_DIRS	library directories to search on this host
#  HLDFLAGS		link flags to use on this host
#  HLDENV		environment variable to set when linking for the host
#  RPATH_ENVVAR		environment variable used to find shared libraries
