Revert "build: enable -Wfloat-equal for compiling"
This reverts commit 25792d64165ad4f5f647a36f087af2d2206a6618.
100 patches later the build output is still noisy with all these warnings.
I'm happy to see this warnings added to the default CFLAGS once the current
warnings have been dealt with.
Enable this warning in the local CFLAGS, get the current warnings fixed,
add it to the efl default flags to make the warning prominent for newly added
