gdb/printcmd.c: Fix printing of Thumb minimal symbols.
In build_address_symbolic we call gdbarch_addr_bits_remove for
symbols in the symbol table but not for minimal symbols. This
causes a failure in gdb.cp/virtfunc.exp on ARM, as the address
of the virtual thunk is given an offset of 1 when in Thumb mode.
gdb/ChangeLog:
2013-06-07 Will Newton <will.newton@linaro.org>
* printcmd.c (build_address_symbolic): Call
gdbarch_addr_bits_remove for text minimal symbols.
