tinymembench: add patch to fix build on Cortex-M

The STM32F4xx series is based on a Cortex-M4 core. This includes a floating-point unit (FPU) which offers hardware support for single-precision IEEE-754 floats. It can improve your application's performance if you are performing floating-point operations. STM32F4 series of high-performance MCUs with DSP and FPU instructions The ARM ® Cortex ®-M4-based STM32F4 MCU series leverages ST’s NVM technology and ART Accelerator™ to reach the industry’s highest benchmark scores for Cortex-M-based microcontrollers with up to 225 DMIPS/608 CoreMark executing from Flash memory at up to 180 MHz operating frequency. Conceptually the Cortex-M4 is a Cortex-M3 plus DSP instructions, and optional floating-point unit (FPU). A core with an FPU is known as Cortex-M4F.

They say they have support for Cortex M4. They say the FPU is active for ARM controllers. The Cortex-M processor series is designed to enable developers to create cost-sensitive and power-constrained solutions for a broad range of devices. Cortex-M4 is a high-performance embedded processor developed to address digital signal control markets that demand an efficient, easy-to-use blend of control and signal processing capabilities. The ARM ® Cortex ® -M4 processor with floating-point unit (FPU) has a 32-bit instruction set (Thumb ® -2 technology) that implements a superset of 16 and 32-bit instructions to maximize code density and performance. This processor implements several features that enable energy-efficient arithmetic and high-performance signal processing including: The MAX32620/MAX32621 feature an Arm ® Cortex ® -M4 with FPU CPU that delivers high-efficiency signal processing, ultra-low power consumption and ease of use. Flexible power modes, an intelligent PMU, and dynamic clock and power gating optimize performance and power consumption for each application. The answer is that the ARM Cortex-M4F has only a *single precision* (float) FPU, and not a double precision (double) FPU. As such, it only can do float operations in hardware but not for double 32-bit Arm® Cortex®-M4, Single Precision Floating Point Unit (FPU), JTAG / SWD debug interfaces; Peripherals: 104 Configurable GPIO pins 3 UART interfaces 3 I2C interfaces 3 SPI interfaces 2 CAN 2.0B Ethernet 10/100 MAC Full-duplex SpaceWire interface DMA controller (4-Channel) 8-Ch Analog-to-digital converter (12-bit, 600ksps) The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm ® single-precision data-processing instructions and all the data types.
