we do not build a libc. Now it builds almost twice as fast.
* Removed logic to build the target GCC. That is never used.

* Replaced config/arm-defconfig-4.2.4 with config/arm920t-defconfig-4.2.4
and config/arm926t-defconfig-4.2.4 because of differences in the
way that soft floating point is handled between these two
architectures.
* Add support for gcc-4.3.3 and the ARM Cortex-M3 processor
* Add support for gcc-4.3.3 and the ARM Cortex-M3 processor (thumb2)
* Add support for binutils 2.19.1

http://buildroot.uclibc.org/ . It has been hacked so that it
can be used to build the following NuttX-compatible toolchains:
o arm-elf toolchain needed for use with the TI C5471 (ARM7),
NXP LPC214x (ARM7), STMicro STR71x (ARM7), and TI DM320
(ARM9) ports provided with the NuttX releases.
o arm-elf toolchain needed for use with the TI C5471 (ARM7TDMI),
NXP LPC214x (ARM7TMDI), STMicro STR71x (ARM7TDMI), Freescale
i.MX1 (ARM920T), and TI DM320 (ARM926EJ-S) provided with the
NuttX releases.
o m68k-elf toolchain (not currently used in any NuttX
configuration).
o arm-elf thumb2 toolchain needed for use with the ARM Cortex-M3
ports provided with the NuttX releases.
o m68hc11-elf toolchain (not currently used in any NuttX
configuration).
o m68k-elf toolchain (not currently used in any NuttX
configuration).
o sh-elf toolchain needed for the SH-1 NuttX port.
o m68hc11-elf toolchain (not currently used in any NuttX
configuration).
o m32c-elf toolchain needed for the Renesas M16C NuttX port.
o sh-elf toolchain needed for the SH-1 NuttX port.
o H8/300 toolchain (not currently used in any NuttX

-You must have already configured Nuttx in <some-dir>nuttx
-download into <some-dir>
-unpack -cd <some-dir>/buildroot
-cp configs/arm-defconfig .config
Supported tool versions include:
o gcc-3.4.6 + binutils-2.17
o gcc-4.2.4 + binutils-2.19
o gcc-4.3.3 + binutils-2.19.1
See the ChangeLog of features/architectgures added in v0.1.5.
Installation instructions:
- You must have already configured Nuttx in <some-dir>/nuttx
- download the buildroot package into <some-dir>
- unpack -cd <some-dir>/buildroot
- cp configs/arm-defconfig .config
- make oldconfig
- make
See configs/README.txt for other configurations and for more detailed
instructions.

then:
- make menuconfig
And set the "Path to the NuttX root directory" appropriately.
