Fix computation of REAL_GNU_TARGET_NAME
The current computation of REAL_GNU_TARGET_NAME is incorrect for non-ARM glibc platforms because it generates something such as mipsel-unknown-linux- as the REAL_GNU_TARGET_NAME. So we correct this by : * Adding "gnu" in the suffix when glibc is used, so that in the previous case we will have mipsel-unknown-linux-gnu * Improving the ARM_EABI code to correctly append "eabi" when glibc is selected, so that we have arm-unknown-linux-gnueabi, and to append "gnueabi" when uclibc is selected, so that we have arm-unknown-linux-uclibcgnueabi. The little trick here is that LIBC and ABI aren't completely orthogonal on ARM. This fixes problems such as : checking host system type... Invalid configuration `mipsel-unknown-linux-': machine `mipsel-unknown-linux' not recognized Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
