Issue with the esp-idf/make/project.mk

[ajaymm58]

With the latest SDK and tools, I noticed the following issue:
At Line #432 and #433, the toolchain version verification returns a null string.
TOOLCHAIN_COMMIT_DESC := $(shell $(CC) --version | sed -E -n 's|xtensa-esp32-elf-gcc\ \(([^)]*).*|\1|gp')
TOOLCHAIN_GCC_VER := $(shell $(CC) --version | sed -E -n 's|xtensa-esp32-elf-gcc\ \(.*\)\ (.*)|\1|gp')

I think that they need to contain ".exe" in the filename:
TOOLCHAIN_COMMIT_DESC := $(shell $(CC) --version | sed -E -n 's|xtensa-esp32-elf-gcc.exe\ \(([^)]*).*|\1|gp')
TOOLCHAIN_GCC_VER := $(shell $(CC) --version | sed -E -n 's|xtensa-esp32-elf-gcc.exe\ \(.*\)\ (.*)|\1|gp')

I use MSYS release from:
https://dl.espressif.com/dl/esp32_win32 ... 170111.zip

I get error as follows:
$ make menuconfig
