Compile failure in cipher/rijndael-aesni.c cites impossible constraint on 'asm':

/var/tmp/portage/dev-libs/libgcrypt-1.7.0/work/libgcrypt-1.7.0/cipher/rijndael-aesni.c: In function ‘_gcry_aes_aesni_ctr_enc’:
/var/tmp/portage/dev-libs/libgcrypt-1.7.0/work/libgcrypt-1.7.0/cipher/rijndael-aesni.c:817:3: error: ‘asm’ operand has impossible constraints
   asm volatile (/* detect if 8-bit carry handling is needed */
   ^

This seems similar at first glance to bug #490276, bug #499994, bug #523726 et al, many of which cite that for them, the error can be avoided by USE=pic.  However, dev-libs/libgcrypt has no 'pic' USE flag.

Comment 1 Kristian Fiskerstrand (RETIRED) gentoo-dev 2016-04-23 17:55:52 UTC 
Can you still reproduce this with gcc 4.9.3?
Comment 2 Phil Stracchino (Unix Ronin) 2016-04-23 18:05:47 UTC 
Hmm,.  I hadn't noticed I'd neglected to switch gcc-config.

Give me a few minutes, I'll retest.
Comment 3 Phil Stracchino (Unix Ronin) 2016-04-23 18:10:58 UTC 
...And the answer appears to be, "With gcc 4.9.3, it works."

Well thats good at least, will see whether we can work with upstream to get it fixed or adding a check to gcc version downstream

Similar problem but different error message here:
