Clang build fails on Windows

[alekulyn]

Pretty straightforward. Changing

telescope-fzf-native.nvim/Makefile

Line 4 in 9ef21b2

CC = gcc

from gcc to clang causes the make command to fail with the following error:

> make
cmd /C mkdir build
clang -O3 -Wall -Werror -fpic -std=gnu99 -shared src/fzf.c -o build/libfzf.dll
clang: error: unsupported option '-fpic' for target 'x86_64-pc-windows-msvc'
make: *** [Makefile:24: build/libfzf.dll] Error 1

I made an issue with the same error, for references #122
