Bug#818745: SIGILL on mips in cephes_igam leading to FTBFS of pymvpa2

[Yaroslav Halchenko <debian@onerussian.com>]

Package: python-scipy
Version: 0.17.0-1
Severity: important

pymvpa2 package FTBFS on mips atm
https://buildd.debian.org/status/fetch.php?pkg=pymvpa2&arch=mips&ver=2.4.3-1&stamp=1458051582
due to 
Program received signal SIGILL, Illegal instruction
which if ran under gdb provides following detail:


Program received signal SIGILL, Illegal instruction.
0x75de5d44 in cephes_igam (a=5.3023991505199126e-315, x=5.2998088236266445e-315) at scipy/special/cephes/igam.c:199
199     scipy/special/cephes/igam.c: No such file or directory.

and dissassemble at that point leads to

0x75de5d44 <+228>:   add.d   $f6,$f6,$f10

scipy package itself seems to ignore failing tests ATM so it doesn't
FTBFS itself although leads to similar illegal instruction crashes in 
https://buildd.debian.org/status/fetch.php?pkg=python-scipy&arch=mips&ver=0.17.0-1%2Bb1&stamp=1457480429
thus hiding the problem and delivering broken scipy on those platforms
