Some targets have a GLIBC_2.0 baseline for libdl, while using GLIBC_2.2 for libc. This means that the generated libc.map file does not have any version nodes for GLIBC_2.0 or GLIBC_2.1. However, moving symbols from libdl into libc needs such version nodes. (Future symbol moves from librt will need this as well.) This kludge is only necessary for symbols predating GLIBC_2.2 because the affected targets use GLIBC_2.2 as the baseline for libc. Given the small number and fixed set of affected architectures, no generic mechanism is implemented, and instead the map file fragment is hard-coded in scripts/versions.mk. The compat_symbol macro already emits the appropriate version strings, so no adjustments are needed there. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
