Thomas Petazzoni f2be0bb278 support/scripts/gen-bootlin-toolchains: improve dependencies of ARM toolchains
The current description of the Bootlin ARM toolchains allows them to
be selected for ARM big endian configurations, which obviously doesn't
work as these Bootlin ARM toolchains are little endian only.

We fix this by adding BR2_arm in the list of conditions for those
toolchains.

Will allow to fix:

# In the below dict:
# - 'conditions' indicate the cumulative conditions under which the
# toolchain will be made available. In several situations, a given
# toolchain is usable on several architectures variants (for
# example, an ARMv6 toolchain can be used on ARMv7)
# - 'test_options' indicate one specific configuration where the
# toolchain can be used. It is used to create the runtime test
# cases. If 'test_options' does not exist, the code assumes it can
# be made equal to 'conditions'
# - 'prefix' is the prefix of the cross-compilation toolchain tools
