[Bug build/9744] New: Building gdb/sim/arm/run does not respect the environments LDFLAGS

["rje at crystalfontz dot com" <sourceware-bugzilla at sourceware dot org>]

I've set up my environment on OS X to find some headers and libraries in other
places.  I did this as so:

CFLAGS=-I/sw/include -I/usr/local/ftdi/include
LDFLAGS=-L/sw/lib -L/usr/local/ftdi/lib
CXXFLAGS=$(CFLAGS)
CPPFLAGS=$(CXXFLAGS) 

When building gdb-6.8 it makes correctly down until the sim/arm directory. 
There it is using gcc to link together the "run" executable but it is not using
the LDFLAGS. Without those it cannot find that libintl is in /sw/lib.

gcc -DHAVE_CONFIG_H     -DPROFILE=1 -DWITH_PROFILE=-1         
-DDEFAULT_INLINE=0           -DMODET -DNEED_UI_LOOP_HOOK -DSIM_TARGET_SWITCHES 
 -I. -I../../../../gdb/sim/arm -I../common -I../../../../gdb/sim/arm/../common
-I../../include -I../../../../gdb/sim/arm/../../include -I../../bfd
-I../../../../gdb/sim/arm/../../bfd -I../../opcodes
-I../../../../gdb/sim/arm/../../opcodes  -I/sw/include -I/usr/local/ftdi/include
-o run \
          run.o libsim.a ../../bfd/libbfd.a ../../opcodes/libopcodes.a -lintl
-liconv -lc ../../libiberty/libiberty.a  
ld: library not found for -lintl
collect2: ld returned 1 exit status
make[5]: *** [run] Error 1
make[4]: *** [all] Error 1
make[3]: *** [all-sim] Error 2
make[2]: *** [all] Error 2
make[1]: *** [cross-gdb] Error 2
make: *** [tools] Error 2

I can work around this by modifying the generated Makefile in sim/arm and adding
the -L/sw/lib to this block.

run$(EXEEXT): $(SIM_RUN_OBJS) libsim.a $(LIBDEPS)
        $(CC) -L/sw/lib $(ALL_CFLAGS) -o run$(EXEEXT) \
          $(SIM_RUN_OBJS) libsim.a $(EXTRA_LIBS)

I'm not sure how to patch it correctly in the configure scripts to pass the
LDFLAGS and have the generated Makefile respect them.
