Cross compiling software for arm with a proprietary toolchain


We have a device here at work running an Arm processor, I have a cross-compiler for the device, it was distributed to our company with the linux distribution we are using on the device (montavista linux). I would love to be able to cross compile some software for this device, however, I really suck at this kind of thing. Whenever I try to cross compile software, I usually get an error like "unrecognized host platform" (I'm paraphrasing obviously), but the toolchain is not that much different from a generic Arm toolchain, just with some extra libraries installed and stuff. I tried using other arm toolchains, but those are a crapshoot, they compile fine, but they don't always run correctly on the device (for instance, busybox).
The reason I get the unrecognized platform error is because the toolchain has a weird prefix on it (arm_v5t_le-) which the configure script can't handle, but if it would just try to cross compile it like it does with other arm targets, it would work fine. How do I make it work?

I have managed to build a new toolchain that works nearly perfectly with the help of buildroot. Buildroot was able to give me more information about my proprietary toolchain which I used to create a new toolchain with the same options. This new toolchain compiles applications very well, however, it appears that it uses the wrong syscalls for network functions, which is not good for my purposes. I believe that this is happening because the device is running a super old kernel (2.6.10), updating the kernel is not an option because we need special drivers for our hardware.
Buildroot fails to build toolchains for kernels that old, which isnt surprising since it is so old. So, I am stuck again.
Anybody have more information about this? Which kernel version changed these syscalls? is there a patch or something to buildroot or the linux kernel that could help me build a toolchain that will work? I have zero experience programming in kernel land, but if somebody could point me to the right place, i could try to modify the syscall numbers in the more modern linux kernel headers if that would work.

Shot in the dark. Old Linux kernel on ARM used OABI system call convention and numbers (kernel 2.4.1 for sure). Some time latter OABI was replaced by EABI - new syscall calling convention and syscall numbers. For some time Linux ARM EABI maintained compatibility with OABI. May be you problem somehow related for OABI/EABI mix.

Thank you, I actually got it to work. I copied the syscall numbers from include/arm/asm/unistd.h from the toolchain distributed by Montavista to the header from linux 2.6.35, built a new toolchain from that and it builds applications that run flawlessly on the target device. Couldn't have asked for a better result.

Could you please attach include/arm/asm/unistd.h from Montavista and original one from your system - I am curious

I guess so. However, I think it is the same as the one from either Linux 2.6.10 or 2.4.17. I don't think its anything special.
it looks like this:
