Building my own tool-chain, missing files

Guest #1442841 
Hello, i'm trying to build my own tool-chain for an arm7tdmi 
(interworking and nofmult).

First, i downloaded the toolchain at 
http://embdev.net/articles/ARM_GCC_toolchain_for_Linux_and_Mac_OS_X , 
and everything was fine.

Now, i built my owm toolchain and everything is right when i'm compiling 
in ARM mode, but i can't compile in interworking mode because i miss 
some files in the directories /interwork (libm.a).

I just put the same flags as the before link, and i patched the 
t-arm-elf (gcc) with the next:

1
MULTILIB_OPTIONS    += mhard-float/msoft-float

2
MULTILIB_DIRNAMES   += fpu soft

3
MULTILIB_EXCEPTIONS += *mthumb/*mhard-float*

4
# 

5
MULTILIB_OPTIONS    += mno-thumb-interwork/mthumb-interwork

6
MULTILIB_DIRNAMES   += normal interwork

7
# 

8
MULTILIB_OPTIONS    += mcpu=arm7

9
MULTILIB_DIRNAMES   += nofmult

10
MULTILIB_EXCEPTIONS += *mthumb*/*mcpu=arm7*


processing the newlib1.17 i had the next errors too:

1
/bin/sh: line 4: arm-elf-ranlib: command not found

2
/bin/sh: line 4: arm-elf-ranlib: command not found

3
make[4]: *** [install-toollibLIBRARIES] Error 127

4
make[3]: *** [install-am] Error 2

5
make[2]: *** [install-recursive] Error 1

6
make[1]: *** [install-target-newlib] Error 2

7
make: *** [install] Error 2



At the moment i can "survive" working in ARM mode xD, but i want to 
compile in Thumb/interworking mode as i guess i will have better 
performance (actually i need it because i have loads of float operations 
in my code).


By the way, i read the performance of the eabi is better for float 
operation. Actually i built a tool-chain with target=arm-none-eabi, and 
it compiles with inter-working without any problems, but i don't know if 
that code will run in a arm7tdmi (AT91SAM7S256). I will test it on 
Thursday.

Thanks in advance.

After this, i'll register myself for edit xD, sorry.

I forgot to mention it, i'm using gcc (Debian 4.4.1-4), and the 
toolchain sources are:

gcc-4.3.3
newlib 1.17.0
binutils 2.19.1
gdb 6.8
