[GEOS] Remove -g options to compilers to reduce size

[giordano]

configure is generating a Makefile with

CFLAGS = -g -O2
CXXFLAGS = -g -O2

Here we just set

CFLAGS=-O2
CXXFLAGS=-O2

These are the sizes of the resulting libraries for x86_64-w64-mingw32:

% ls -lh GEOS.v3.8.0.x86_64-w64-mingw32/bin 
total 3.8M
-r-xr-xr-x 1 mose mose 1.3K Nov 26 02:21 geos-config
-r-xr-xr-x 1 mose mose 3.0M Nov 26 02:21 libgeos-3-8-0.dll
-r-xr-xr-x 1 mose mose 815K Nov 26 02:21 libgeos_c-1.dll

I think this is a good improvement compared to the current situation, without doing any magic. Ref #234. CC: @jaakkor2 @visr

If I further manually run strip on the libraries I get

% ls -lh GEOS.v3.8.0.x86_64-w64-mingw32/bin
total 1.7M
-r-xr-xr-x 1 mose mose 1.3K Nov 26 02:21 geos-config
-r-xr-xr-x 1 mose mose 1.5M Nov 26 02:35 libgeos-3-8-0.dll
-r-xr-xr-x 1 mose mose 220K Nov 26 02:35 libgeos_c-1.dll

Great!

If I strip the Linux libraries from the installed version (on Julia v1.3.0-rc5, LIbGEOS#artifact), I get

ERROR: InitError: could not load library "/home/jaakkor2/.julia/artifacts/7e3b40b7bb49e6ecd2ba78970ab38051a518acce/lib/libgeos_c.so"
/home/jaakkor2/.julia/artifacts/7e3b40b7bb49e6ecd2ba78970ab38051a518acce/lib/libgeos_c.so: ELF load command address/offset not properly aligned

🤔

Thanks Mosè, this looks like a good improvement to me.

Yeah, let's try not to use strip; it does things that patchelf finds unpalatable.
