The -taso switch was quite useful 25 years ago for porting 32-bit code with broken integer-pointer casting. Not anymore. The EF_ALPHA_32BIT Linux support is going to be dropped in kernel v6.14 [1], NetBSD and OpenBSD never had it, so there is no point in keeping the -taso option around. Also remove alpha special case that uses -taso from gdb.base/dump.exp in gdb testsuite.
