A couple warnings in gmp.texi

[Antonio Diaz Diaz]

Hello,

When running 'makeinfo gmp.texi' with makeinfo 4.13 and GMP 6.3.0 I get a 
couple warnings:

gmp.texi:2449: warning: `.' or `,' must follow @xref, not `)'.
gmp.texi:2449: warning: for cross-references in parentheses, use @pxref.
gmp.texi:9079: warning: `.' or `,' must follow @xref, not `b'.

I have fixed them with the patch below.

The warnings are still present in the devel version of gmp.texi (at lines 
2449 and 9080).

BTW, I would suggest to pass '--no-split' to makeinfo because the full info 
manual is not so large (about 112 kB compressed).

Best regards,
Antonio.
