mk: use icc default inline limit

ICC build time
Before this patch (bnx2x PMD enabled [1])
real    8m16.622s

After this patch (bnx2x enabled)
real    0m35.140s

[1]
bnx2x cause the build take a lot, otherwise build times are more sane
numbers.

ICC has a default inline limit and when this limit is hit it generates
a warning, and in DPDK this breaks the build.

Previous solution was to remove the inline limit, which does more
aggressive inlining and build may take too much time.

This patch keeps the default inline limits, but prevents the warning ICC
generates.
