Define the AT_MINSIGSTKSZ in generic Linux. It is already used as generic
ABI in glibc's generic elf.h, and this define will prevent future namespace
conflicts. In particular, x86 is also using this generic definition.

I know glibc's comment says a similar thing but the correct thing to say
here should be "minimal stack size for signal delivery" or so. Even the
variable name alludes to that too.
