[Buildroot] [git commit master] Fix the computation of REAL_GNU_TARGET_NAME

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=5e1fbd2c33452bd7480583ccc5cfc50546ac010d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When the selected C library is glibc, the C library shouldn't be
mentionned in REAL_GNU_TARGET_NAME. In other words:

 arm-unknown-linux-uclibcgnueabi must be used for uClibc
 arm-unknown-linux-gnueabi must be used for glibc

This fixes the build of GDB on the target, as reported by Quotient
Remainder <quotientvremainder at gmail.com>.
