Comment (by mcalhoun@…):

 GMP has a script {{{config.guess}}} that prints "the host system CPU-
 VENDOR-OS."[[BR]]
 The CPU value is used to set {{{-mtune}}}, set {{{-march}}}, and select
 assembly files to use.[[BR]]
 The {{{+core2}}} variant forces the CPU value to be core2.[[BR]]
 With a little trial and error, we can probably narrow down the
 problem.[[BR]]
 Since I can not reproduce this problem, I will need a little help.

 1. Does {{{port test gmp}}} report any errors?
 2. What is the output of {{{config.guess }}} (located in the GMP source
 directory)?

 With this information, we can modify the CPU specific code in
 {{{configure}}} that is different from (the working) core2 code.
