Fix gdb.base/define.exp

[Nathan Sidwell <nathan@codesourcery.com>]

[-- Attachment #1: Type: text/plain, Size: 442 bytes --]

the define.exp test requires malloc to be in the target executable

whilenospace
evaluation of this expression requires the program to have a function "malloc".
(gdb) FAIL: gdb.base/define.exp: test whilenospace is parsed correctly

This patch forces malloc to be there. ok?
