Different binary size: make vs cmake (GIT8266O-367)

[THKDev]

Environment

• Development Kit: ESP8266
• IDF version : d1cfba3 (branch v3.3)
• Development Env: Make
• Operating System: Linux
• Power Supply: external 3.3V

Problem Description

Resulting size of binary differs between cmake and make environment.

Steps to repropduce

Step one:

get-started/hello_world git:(release/v3.3) ▶ make size
Total sizes:
 DRAM .data size:    1372 bytes
 DRAM .bss  size:    8912 bytes
Used static DRAM:   10284 bytes (  88020 available, 10.5% used)
Used static IRAM:   25220 bytes (  23932 available, 51.3% used)
      Flash code:  144452 bytes
    Flash rodata:   18624 bytes
Total image size:~ 189668 bytes (.bin may be padded larger)

Step two

get-started/hello_world git:(release/v3.3) ▶ mkdir build
get-started/hello_world git:(release/v3.3) ▶ cd build
hello_world/build git:(release/v3.3) ▶ cmake ..
hello_world/build git:(release/v3.3) ▶ make size
Scanning dependencies of target size
Total sizes:

Used static IRAM:   25220 bytes (  23932 available, 51.3% used)
      Flash code:  144464 bytes
