The introduction of the EABIhf ABI requires a few updates to the configuration options for external toolchains, in order to ensure that the user doesn't do any invalid selection. In detail: * The Linaro ARM toolchains now depend on BR2_ARM_EABIHF, because that's the ABI they use, and it is incompatible with EABI. The comment about the availability of Linaro toolchains is updated to inform users selecting EABI that they should select EABIhf if they want to see Linaro toolchains. * The Sourcery CodeBench toolchains now depend on BR2_ARM_EABI, because that's the ABI they use. A comment is added to inform users that have selected EABIhf that Sourcery CodeBench are only available when EABI is used. * The Arago toolchains now depend on BR2_ARM_EABI, because that's the ABI they use. The description of the ARMv7 Arago toolchain is also slightly improved. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

GCC 2013.06 (based on gcc 4.8), Linaro GDB 2013.06 (based on
