8 tests failing during make check with floating point exceptions

Greetings,

I am trying to install libpng 1.6.37 on a CentOS 7 machine and am failing
some tests when running make check (see below).

  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-957.10.1.el7.x86_64
      Architecture: x86-64

I am using Intel compilers.

./test-suite.log contents:

Gamma correction error summary

The printed value is the maximum error in the pixel values
calculated by the libpng gamma correction code.  The error
is calculated as the difference between the output pixel
value (always an integer) and the ideal value from the
libpng specification (typically not an integer).

Expect this value to be less than .5 for 8 bit formats,
less than 1 for formats with fewer than 8 bits and a small
number (typically less than 5) for the 16 bit formats.
For performance reasons the value for 16 bit formats
increases when the image file includes an sBIT chunk.

Basic gamma correction:
  2 bit gray:  127.07023
  4 bit gray:  127.07023
  8 bit gray:  128.32752
