5739f705ee Use integral constants
The compiler is smart enough to convert those into double for powerpc,
but if we put them as doubles, it adds overhead by performing those
operations in floating point mode.

6f2e90e78f Make mantissa type of mp_no configurable
The mantissa of mp_no is intended to take only integral values.  This
is a relatively good choice for powerpc due to its 4 fpus, but not for
other architectures, which suffer due to this choice.  This change
makes the default mantissa a long integer and allows powerpc to
override it.  Additionally, some operations have been optimized for
integer manipulation, resulting in a significant improvement in
performance.

e42a38dd9d BZ#13889: expl (709.75) wrongly overflows for ldbl-128ibm
The patch increase the high value to check if expl overflows. Current
high mark value is not really correct, the algorithm accepts high values.
It also adds a correct wrapper function to check for overflow and underflow.

2e0fb52187 BZ#11120: fix x86_64/strcmp.S NOT_IN_libc safeguards
Due to a typo repeated several times, this bug hasn't been fixed yet,
despite being marked as resolved in glibc 2.12.

* sysdeps/x86_64/strcmp.S: Replace all occurrences of NOT_IN_lib
with NOT_IN_libc.

adbb8027be Remove PIPE_BUF Linux-specific code
Fixes BZ #12723

The variable pipe buffer size does nothing to the value of PIPE_BUF,
since the number of bytes that are atomically written is still
PIPE_BUF on Linux.
