Build of the branch local-set-param with muslc/qsort

To facilitate others to test my GLPK/GLPSOL extensions I'm making available binaries cross compiled on lLinux.
This build uses muslc/qsort and with it now using the "--cuts" option also improve performance in native builds like webassemby build, except the windows 32bits build that has performance degraded.

Build of the branch local-set-param with "long double"

This binaries where compiled with the experimental WITH_LONG_DOUBLE defined, that means it's using "long double" instead of "double" for the solver (GMPL remain using doubles), in my tests as it is now it's around 2 times slower than using "doubles" and for some problems it shows a different solution, it probably can benefit from tunning several constants in src/glpk_real.h
