gettext-tools 0.21.1 failing on NetBSD sparc (32 bit)

[vom513]

Hello,

I am able to build gettext-tools 0.21 on NetBSD sparc just fine.  0.21.1 fails.  Here is my NetBSD bug report:

http://gnats.netbsd.org/57425

So it seems to fail on ftello bits.  However (and I’m not sure this is related ? cause ?) - I notice in my 0.21 tree - gcc runs as expected, but in 0.21.1 - it runs -mcpu=v9.

I see this commit, which is the closest thing I can find regarding Sparc related stuff in 0.21.2:

https://git.savannah.gnu.org/gitweb/?p=gettext.git;a=commitdiff;h=45c8d0aec9023ddf4c0ab9f12d67fc2f7e66df2c

Seems like the reporter was having a different issue.  But the mention of 32-bit caught my eye.

Also, another difference I see between the versions is this (sorry it’s a bit long…):

2022Q4-qemu$ pwd

/usr/pkgsrc/devel/gettext-tools/work/gettext-0.21/gettext-tools/gnulib-m4

2022Q4-qemu$ ls -la sparc*

ls: sparc*: No such file or directory

CVS-qemu$ pwd

/usr/pkgsrc/devel/gettext-tools/work/gettext-0.21.1/gettext-tools/gnulib-m4

CVS-qemu$ ls -la sparc*
