[Buildroot] libgcc build error on arm

[Buildroot] libgcc build error on arm

[Amit Uttamchandani]

Using the latest git source I get following build error when building a
toolchain for arm (build log can be found at end of message):

I tried the following approaches:

 1. Build without shared libs - fails
 2. Build with shared libs - fails
 3. Add '_nofpu' suffix for soft float toolchains - fails
 4. Git clone from scratch and rebuild - fails

For the build options I used all the default from Buildroot. Arch build
options:

BR2_armeb=y
BR2_generic_arm=y
BR2_ARM_TYPE="GENERIC_ARM"
BR2_ARM_EABI=y
BR2_ARCH="armeb"
BR2_ENDIAN="LITTLE"
BR2_GCC_TARGET_ABI="aapcs-linux"

Any help would be appreciated.

Thanks.

Solved by using the following:

Target architecture: arm
Target architecture variant: generic_arm
Target ABI: OABI

Thanks,

Still, I recommend using EABI.
