I want to install 32 bit gettext by homebrew:

brew install gettext --32-bit

But when it is still x86_64 version:

file /usr/local/Cellar/gettext/0.18.2/lib/libgettextlib-0.18.2.dylib 

/usr/local/Cellar/gettext/0.18.2/lib/libgettextlib-0.18.2.dylib: Mach-O 64-bit dynamically linked shared library x86_64

You probably want to use brew install gettext --universal, which will build a universal ("fat") binary containing both 32-bit and 64-bit code. There's no --32-bit option; see brew info gettext to see what options are supported.

$ brew install gettext --universal
[...snip...]
$ file /usr/local/Cellar/gettext/0.18.2/lib/libgettextlib-0.18.2.dylib
/usr/local/Cellar/gettext/0.18.2/lib/libgettextlib-0.18.2.dylib: Mach-O universal binary with 2 architectures
/usr/local/Cellar/gettext/0.18.2/lib/libgettextlib-0.18.2.dylib (for architecture i386):    Mach-O dynamically linked shared library i386
/usr/local/Cellar/gettext/0.18.2/lib/libgettextlib-0.18.2.dylib (for architecture x86_64):  Mach-O 64-bit dynamically linked shared library x86_64
