1284764Semaste# This is the linker host specific file.  This is invoked by the
2284764Semaste# autoconf generated configure script.  Putting it in a separate shell
3284764Semaste# file lets us skip running autoconf when modifying host specific
4# information.

7#  HDEFINES		host specific compiler flags
8#  HOSTING_CRT0		crt0.o file used for bootstrapping
9#  HOSTING_LIBS		libraries used for bootstrapping
10#  NATIVE_LIB_DIRS	library directories to search on this host
11#  HLDFLAGS		link flags to use on this host
12#  HLDENV		environment variable to set when linking for the host
