[Bug build/10752] New: GDB 7.0 can't be built multiarch on Darwin 10.0

[dusk at woofle dot net]

Attempting to build a two-way universal gdb7 on Darwin 10.0 (Mac OS 10.6) is
impossible, as the configure script lacks a --disable-dependency-tracking
option. Configure is successful, but the build errors out in BFD with

/bin/sh ./libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.
-I./../include  -I./../intl -DBINDIR='"/usr/local/bin"'  -W -Wall
-Wstrict-prototypes -Wmissing-prototypes -Werror -arch i386 -arch x86_64 -MT
archive.lo -MD -MP -MF .deps/archive.Tpo -c -o archive.lo archive.c
libtool: compile:  gcc -DHAVE_CONFIG_H -I. -I. -I. -I./../include -I./../intl
-DBINDIR=\"/usr/local/bin\" -W -Wall -Wstrict-prototypes -Wmissing-prototypes
-Werror -arch i386 -arch x86_64 -MT archive.lo -MD -MP -MF .deps/archive.Tpo -c
archive.c -o archive.o
gcc-4.0: -E, -S, -save-temps and -M options are not allowed with multiple -arch
flags

The BFD configure script has the requisite option, but it has to be run
manually. When this is done, though, the build still fails:

/bin/sh ./libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.
-I./../include  -I./../intl -DBINDIR='"/usr/local/bin"'  -W -Wall

This type of error is typical of builds which assume that the word size is
constant, which isn't the case in multiarch.
