[PATCH 02/11] alpha: set DF_TEXTREL rather than DT_TEXTREL in info->flags

This patch corrects a long-standing issue in the alpha ELF linker where DT_TEXTREL was incorrectly OR-ed into info->flags as DF_TEXTREL. This misuse led to misinterpretations by the dynamic linker, causing shared libraries with text relocations in read-only sections to be treated as if linked with -Bsymbolic. It also caused incorrect relaxation of TLS references. The fix replaces the incorrect DT_TEXTREL with the proper DF_TEXTREL flag, resolving these issues.
