Technically speaking, libdrm is not a mandatory dependency for the ATI
driver. It seems to only be mandatory if you want to enable DRI support.

Moreover, the fact that libdrm-radeon is only available on x86 and
x86-64 is wrong. It might have been the case back when it had a
dependency on libpciaccess, but it's no longer the case, and I've just
tested: one can build libdrm-radeon for ARM without any problem:

$ file output/target/usr/lib/libdrm_radeon.so.1.0.1 
output/target/usr/lib/libdrm_radeon.so.1.0.1: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, stripped
