for IBM AIX powerpc architecture, because I couldn't find a __ppc__ or __powerpc__ defined by gcc on AIX. Is it correct to use _POWER?
Sounds right, sometimes the macros don't have the trailing "__". As always because we don't know why you need the processor architecture we can't advise you more.
As a couple of suggestions you may be trying to find out if you are big or little endian, or perhaps 32 or 64 bit.
In the first case for macros like "_BYTE_ORDER", "_LITTLE_ENDIAN" and "_BIG_ENDIAN".
In the second case look for macros like _LP64 or __LP64__ or even "_WIN64".
This may end up long winded but worth it in the long run, I have a single file I extend as I test more architectures.
Can anybody help me in finding out a solution for the problem below?

DESCRIPTION
The following commands will return a true value (exit code of 0) if you are using an instruction set that the command name indicates.
sun True if you are on a Sun system.
iAPX286 True if you are on a computer using an iAPX286 processor.
i386 True if you are on a computer using an iAPX386 processor.
pdp11 True if you are on a PDP-11/45tm or PDP-11/70tm.
sparc True if you are on a computer using a SPARC-family processor.
u3b True if you are on a 3B20 computer.
u3b2 True if you are on a 3B2 computer.
u3b5 True if you are on a 3B5 computer.
u3b15 True if you are on a 3B15 computer.
vax True if you are on a VAX-11/750tm or VAX-11/780tm.
u370 True if you are on an IBM(R) System/370tm computer.
The commands that do not apply will return a false (non-zero) value. These commands are often used within makefiles (see make(1S)) and
shell scripts (see sh(1)) to increase portability.
