toolchain-external: adjust logic to support Linaro 2012.05
The check_glibc function verifies that the C library of the external toolchain is glibc. To do so, it verified that a file matching ld-linux*.so.* or ld.so.* was found in the lib/ directory of the toolchain's sysroot. However, with the Linaro 2012.05 toolchain, the lib/ directory contains two links named ld-linux-armhf.so.3 and ld-linux.so.3, which means that the first ld-linux*.so.* wildcard expression expands to two files, which generates a syntax error for the "test" program. We replace that with a more elaborate find+wc combination to determine whether at least one matching file is present. The check_arm_abi function verifies the ABI of an ARM toolchain. For EABI, it tested that the target name ends with eabi. However, with Linaro 2012.05, the tuple is now arm-linux-gnueabihf (for hard float), so we have to adjust the logic to accept this additional "hf" specification in the tuple.
