CC_FOR_BUILD is not recognized

To solve this problem, you can modify the macro definition

$(CC)-o $@ ${srcdir} / texinfo2man.c

Extension

Autoconf cached variables (CC_FOR_BUILD), search autoconf script did not find any information

CC_FOR_BUILD is described in detail in config/config.guess under the folder directory.

# CC_FOR_BUILD-compiler used by this script. Note that the use of a

# compiler to aid in system detection is discouraged as it requires

# temporary files to be created and, as you can see below, it is a

# headache to deal with in a portable fashion.

# Historically, `CC_FOR_BUILD' used to be named `HOST_CC'. We still

# use `HOST_CC' if defined, but it is deprecated.

The macro definition is defined in other open source

Secp256k1/build-aux/m4/ax_prog_cc_for_build.m4

This macro searches for a C compiler that generates native executables

# that is a C compiler that surely is not a cross-compiler. This can be

# useful if you have to generate source code at compile-time like for

# example GCC does.

#

# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything

# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).

# The value of these variables can be overridden by the user by specifying

# a compiler with an environment variable (like you do for standard CC).

Config.guess here assigns values to the macro definition
