travis: simplify cross-compilation setup
Following Maxim's idea use apt-get to download and install cross-packages.

example: ipfragreass: fix compilation with clang
Clang 3.8 is stricter than GCC wrt register allocation vs 128-bit variables. Sometimes it can not understand using 128-bit var in place of 64-bit register resulting in the following errors:
/odp_ipfragreass_atomics_arm.h:18:51: error: value size does not match register size specified by the constraint and modifier [-Werror,-Wasm-operand-widths] __asm__ volatile("ldaxp %0, %H0, [%1]" : "=&r" (old) ^ ./odp_ipfragreass_atomics_arm.h:18:27: note: use constraint modifier "w" __asm__ volatile("ldaxp %0, %H0, [%1]" : "=&r" (old)
Explicitly pass low and high parts of 128-bit variable in separate assembly parameters.
